In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the userspace API. However, the code allows larger values such as 23.

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1070 advisory.

  - In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the     userspace API. However, the code allows larger values such as 23. (CVE-2015-9289)

  - The KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to     the current task's default request-key keyring via the request_key() system call, allowing a local user     to use a sequence of crafted system calls to add keys to a keyring with only Search permission (not Write     permission) to that keyring, related to construct_get_dest_keyring() in security/keys/request_key.c.
    (CVE-2017-17807)

  - The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num     from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds     (OOB) read that potentially allows arbitrary read in the kernel address space. (CVE-2018-19985)

  - An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during     the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.
    (CVE-2018-20169)

  - In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and     panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to     CVE-2013-4343. (CVE-2018-7191)

  - A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before     4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware     could use this flaw to issue a specially crafted ioctl function call and cause the system to crash.
    (CVE-2019-10207)

  - In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel     produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple     destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and     thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page     that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (CVE-2019-10638)

  - The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel     address disclosure), leading to a KASLR bypass. Specifically, it is possible to extract the KASLR kernel     image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and     ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash     collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This     key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via     enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the     attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled     IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic     is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the     attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP     addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to     have a dependency on an address associated with a network namespace. (CVE-2019-10639)

  - The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs (such as /bin/su) because     install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the     ptrace_may_access() check has a race condition when reading /proc/pid/stat. (CVE-2019-11190)

  - The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a     local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command,     because a name field may not end with a '\0' character. (CVE-2019-11884)

  - An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash). NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL     pointer dereference (CVE-2019-12382)

  - In arch/x86/lib/insn-eval.c in the Linux kernel before 5.1.9, there is a use-after-free for access to an     LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds     violation. (CVE-2019-13233)

  - In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and     head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an     unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by     default. (CVE-2019-14283)

  - A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params()     function of Marvell Wifi Driver. (CVE-2019-14815)

  - An issue was discovered in the Linux kernel before 5.1.17. There is a NULL pointer dereference caused by a     malicious USB device in the sound/usb/line6/pcm.c driver. (CVE-2019-15221)

  - An issue was discovered in the Linux kernel before 5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check     the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)

  - A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs.
    As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it     is possible for the specified target task to perform an execve() syscall with setuid execution before     perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check     and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged     execve() calls. This issue affects kernel versions before 4.8. (CVE-2019-3901)

  - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable     to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source,     the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver     receives the firmware event frame from the host, the appropriate handler is called. This frame validation     can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event     frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi     packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
    More typically, this vulnerability will result in denial-of-service conditions. (CVE-2019-9503)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The usbvision driver in the Linux kernel package 3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red     Hat Enterprise Linux (RHEL) 7.1 allows physically proximate attackers to cause a denial of service (panic)     via a nonzero bInterfaceNumber value in a USB device descriptor. (CVE-2015-7833)

  - arch/arm64/kernel/sys.c in the Linux kernel before 4.0 allows local users to bypass the 'strict page     permissions' protection mechanism and modify the system-call table, and consequently gain privileges, by     leveraging write access. (CVE-2015-8967)

  - In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the     userspace API. However, the code allows larger values such as 23. (CVE-2015-9289)

  - The evm_verify_hmac function in security/integrity/evm/evm_main.c in the Linux kernel before 4.5 does not     properly copy data, which makes it easier for local users to forge MAC values via a timing side-channel     attack. (CVE-2016-2085)

  - The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel before 4.5.5 does not     initialize a certain data structure, which allows local users to obtain sensitive information from kernel     stack memory by reading a Netlink message. (CVE-2016-4486)

  - Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel     before 4.6 allows local users to obtain sensitive information from kernel memory by changing a certain     length value, aka a 'double fetch' vulnerability. (CVE-2016-6130)

  - A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost     functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A     privileged guest user able to pass descriptors with invalid length to the host when migration is underway,     could use this flaw to increase their privileges on the host. (CVE-2019-14835)

  - In do_epoll_ctl and ep_loop_check_proc of eventpoll.c, there is a possible use after free due to a logic     error. This could lead to local escalation of privilege with no additional execution privileges needed.
    User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-147802478References: Upstream kernel (CVE-2020-0466)

  - A race condition was found in the Linux kernels implementation of the floppy disk drive controller driver     software. The impact of this issue is lessened by the fact that the default permissions on the floppy     device (/dev/fd0) are restricted to root. If the permissions on the device have changed the impact changes     greatly. In the default configuration root (or equivalent) permissions are required to attack this flaw.
    (CVE-2021-20261)

  - There is a flaw reported in the Linux kernel in versions before 5.9 in     drivers/gpu/drm/nouveau/nouveau_sgdma.c in nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The issue     results from the lack of validating the existence of an object prior to performing operations on the     object. An attacker with a local account with a root privilege, can leverage this vulnerability to     escalate privileges and execute code in the context of the kernel. (CVE-2021-20292)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - An issue was discovered in the Linux kernel through 5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI     subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the     pointer to an iscsi_transport struct in the kernel module's global variables. (CVE-2021-27363)

  - An issue was discovered in the Linux kernel through 5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged user to craft Netlink messages. (CVE-2021-27364)

  - An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a     Netlink message. (CVE-2021-27365)

  - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
    (CVE-2021-30002)

  - ** DISPUTED ** fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS export of a     subdirectory of a filesystem, allows remote attackers to traverse to other parts of the filesystem via     READDIRPLUS. NOTE: some parties argue that such a subdirectory export is not intended to prevent this     attack; see also the exports(5) no_subtree_check default behavior. (CVE-2021-3178)

  - An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-     device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with     special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash or     a leak of internal kernel information. The highest threat from this vulnerability is to system     availability. (CVE-2021-31916)

  - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because     the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads     to writing an arbitrary value. (CVE-2021-33033)

  - An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute code in the kernel, aka CID-34b1a1ce1458.
    (CVE-2021-3347)

  - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer     allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an     unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)

  - A flaw was found in the Nosy driver in the Linux kernel. This issue allows a device to be inserted twice     into a doubly-linked list, leading to a use-after-free when one of these devices is removed. The highest     threat from this vulnerability is to confidentiality, integrity, as well as system availability. Versions     before kernel 5.12-rc6 are affected (CVE-2021-3483)

  - kernel/module.c in the Linux kernel before 5.12.14 mishandles Signature Verification, aka     CID-0c18f29aae7c. Without CONFIG_MODULE_SIG, verification that a kernel module is signed, for loading via     init_module, does not occur for a module.sig_enforce=1 command-line argument. (CVE-2021-35039)

  - In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the     userspace API. However, the code allows larger values such as 23. (CVE-2015-9289)

  - An issue was discovered in the Linux kernel before 4.18.7. In create_qp_common in     drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never initialized, resulting in a leak of     stack memory to userspace. (CVE-2018-20855)

  - An information disclosure vulnerability exists when certain central processing units (CPU) speculatively     access memory, aka 'Windows Kernel Information Disclosure Vulnerability'. This CVE ID is unique from     CVE-2019-1071, CVE-2019-1073. (CVE-2019-1125)

  - An issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when     megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c.
    This causes a Denial of Service, related to a use-after-free. (CVE-2019-11810)

  - In parse_hid_report_descriptor in drivers/input/tablet/gtco.c in the Linux kernel through 5.2.1, a     malicious USB device can send an HID report that triggers an out-of-bounds write during generation of     debugging messages. (CVE-2019-13631)

  - In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and     head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an     unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by     default. (CVE-2019-14283)

  - In the Linux kernel before 5.2.3, drivers/block/floppy.c allows a denial of service by setup_format_params     division-by-zero. Two consecutive ioctls can trigger the bug: the first one should set the drive geometry     with .sect and .rate values that make F_SECT_PER_TRACK be zero. Next, the floppy format operation should     be called. It can be triggered by an unprivileged local user even when a floppy disk has not been     inserted. NOTE: QEMU creates the floppy device by default. (CVE-2019-14284)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has kernel packages installed that are affected by multiple vulnerabilities:

  - In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the     userspace API. However, the code allows larger values such as 23. (CVE-2015-9289)

  - The KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to     the current task's default request-key keyring via the request_key() system call, allowing a local user     to use a sequence of crafted system calls to add keys to a keyring with only Search permission (not Write     permission) to that keyring, related to construct_get_dest_keyring() in security/keys/request_key.c.
    (CVE-2017-17807)

  - An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during     the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.
    (CVE-2018-20169)

  - In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and     panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to     CVE-2013-4343. (CVE-2018-7191)

  - The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-     free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - ** DISPUTED ** An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the     Linux kernel through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause     a denial of service (NULL pointer dereference and system crash). NOTE: The vendor disputes this issues as     not being a vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance     for a NULL pointer dereference. (CVE-2019-12382)

  - In arch/x86/lib/insn-eval.c in the Linux kernel before 5.1.9, there is a use-after-free for access to an     LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds     violation. (CVE-2019-13233)

  - In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and     head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an     unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by     default. (CVE-2019-14283)

  - There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip     driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly     execute arbitrary code. (CVE-2019-14816)

  - A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before     4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection     negotiation during the handling of the remote devices country settings. This could allow the remote device     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895)

  - The fix for CVE-2019-11599, affecting the Linux kernel before 5.0.10 was not complete. A local user could     use this flaw to obtain sensitive information, cause a denial of service, or possibly have other     unspecified impacts by triggering a race condition with mmget_not_zero or get_task_mm calls.
    (CVE-2019-14898)

  - A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell     WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a     denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the     availability of the system. If code execution occurs, the code will run with the permissions of root. This     will affect both confidentiality and integrity of files on the system. (CVE-2019-14901)

  - An issue was discovered in the Linux kernel before 5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service. (CVE-2019-15916)

  - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a     long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

  - rtl_p2p_noa_ie in drivers/net/wireless/realtek/rtlwifi/ps.c in the Linux kernel through 5.3.6 lacks a     certain upper-bound check, leading to a buffer overflow. (CVE-2019-17666)

  - A flaw was found in the fix for CVE-2019-11135, in the Linux upstream kernel versions before 5.5 where,     the way Intel CPUs handle speculative execution of instructions when a TSX Asynchronous Abort (TAA) error     occurs. When a guest is running on a host CPU affected by the TAA flaw (TAA_NO=0), but is not affected by     the MDS issue (MDS_NO=1), the guest was to clear the affected buffers by using a VERW instruction     mechanism. But when the MDS_NO=1 bit was exported to the guests, the guests did not use the VERW mechanism     to clear the affected buffers. This issue affects guests running on Cascade Lake CPUs and requires that     host has 'TSX' enabled. Confidentiality of data is the highest threat associated with this vulnerability.
    (CVE-2019-19338)

  - A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs.
    As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it     is possible for the specified target task to perform an execve() syscall with setuid execution before     perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check     and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged     execve() calls. This issue affects kernel versions before 4.8. (CVE-2019-3901)

  - In the Android kernel in Pixel C USB monitor driver there is a possible OOB write due to a missing bounds     check. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation. (CVE-2019-9456)

  - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable     to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source,     the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver     receives the firmware event frame from the host, the appropriate handler is called. This frame validation     can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event     frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi     packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
    More typically, this vulnerability will result in denial-of-service conditions. (CVE-2019-9503)

  - A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7.
    This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into     the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO     restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate     that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer     dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network     user to crash the system kernel, resulting in a denial of service. (CVE-2020-10711)

    (CVE-2017-17807)

  - The function hso_get_config_data in drivers/net/usb/hso.c in the Linux kernel through 4.19.8 reads if_num     from the USB device (as a u8) and uses it to index a small array, resulting in an object out-of-bounds     (OOB) read that potentially allows arbitrary read in the kernel address space. (CVE-2018-19985)

  - An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during     the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.
    (CVE-2018-20169)

  - In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and     panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to     CVE-2013-4343. (CVE-2018-7191)

  - A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before     4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware     could use this flaw to issue a specially crafted ioctl function call and cause the system to crash.
    (CVE-2019-10207)

  - In the Linux kernel before 5.1.7, a device can be tracked by an attacker using the IP ID values the kernel     produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple     destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and     thereby obtain the hashing key (via enumeration). An attack may be conducted by hosting a crafted web page     that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. (CVE-2019-10638)

  - The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel     address disclosure), leading to a KASLR bypass. Specifically, it is possible to extract the KASLR kernel     image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and     ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash     collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This     key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via     enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the     attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled     IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic     is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the     attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP     addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to     have a dependency on an address associated with a network namespace. (CVE-2019-10639)

  - The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs (such as /bin/su) because     install_exec_creds() is called too late in load_elf_binary() in fs/binfmt_elf.c, and thus the     ptrace_may_access() check has a race condition when reading /proc/pid/stat. (CVE-2019-11190)

  - The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a     local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command,     because a name field may not end with a '\0' character. (CVE-2019-11884)

  - An issue was discovered in drm_load_edid_firmware in drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr, which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash). NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is handled sufficiently and there is no chance for a NULL     pointer dereference (CVE-2019-12382)

  - In arch/x86/lib/insn-eval.c in the Linux kernel before 5.1.9, there is a use-after-free for access to an     LDT entry because of a race condition between modify_ldt() and a #BR exception for an MPX bounds     violation. (CVE-2019-13233)

  - In the Linux kernel through 5.2.1 on the powerpc platform, when hardware transactional memory is disabled,     a local user can cause a denial of service (TM Bad Thing exception and system crash) via a sigreturn()     system call that sends a crafted signal frame. This affects arch/powerpc/kernel/signal_32.c and     arch/powerpc/kernel/signal_64.c. (CVE-2019-13648)

  - In the Linux kernel before 5.2.3, set_geometry in drivers/block/floppy.c does not validate the sect and     head fields, as demonstrated by an integer overflow and out-of-bounds read. It can be triggered by an     unprivileged local user when a floppy disk has been inserted. NOTE: QEMU creates the floppy device by     default. (CVE-2019-14283)

  - There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell     wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or     possibly execute arbitrary code. (CVE-2019-14814)

  - A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params()     function of Marvell Wifi Driver. (CVE-2019-14815)

  - An issue was discovered in drivers/scsi/qedi/qedi_dbg.c in the Linux kernel before 5.1.12. In the     qedi_dbg_* family of functions, there is an out-of-bounds read. (CVE-2019-15090)

  - An issue was discovered in the Linux kernel before 5.0.10. There is a use-after-free in the sound     subsystem because card disconnection causes certain data structures to be deleted too early. This is     related to sound/core/init.c and sound/core/info.c. (CVE-2019-15214)

  - An issue was discovered in the Linux kernel before 5.1.17. There is a NULL pointer dereference caused by a     malicious USB device in the sound/usb/line6/pcm.c driver. (CVE-2019-15221)

  - An issue was discovered in the Linux kernel before 5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in net/wireless/nl80211.c in the Linux kernel through 5.2.17. It does not check     the length of variable elements in a beacon head, leading to a buffer overflow. (CVE-2019-16746)

  - The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is     not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to     arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. (CVE-2019-18660)

  - A race condition in perf_event_open() allows local attackers to leak sensitive data from setuid programs.
    As no relevant locks (in particular the cred_guard_mutex) are held during the ptrace_may_access() call, it     is possible for the specified target task to perform an execve() syscall with setuid execution before     perf_event_alloc() actually attaches to it, allowing an attacker to bypass the ptrace_may_access() check     and the perf_event_exit_task(current) call that is performed in install_exec_creds() during privileged     execve() calls. This issue affects kernel versions before 4.8. (CVE-2019-3901)

  - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An     attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations     before the required authentication process has completed. This could lead to different denial-of-service     scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already     existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge     Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)

  - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable     to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source,     the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver     receives the firmware event frame from the host, the appropriate handler is called. This frame validation     can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event     frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi     packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
    More typically, this vulnerability will result in denial-of-service conditions. (CVE-2019-9503)

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):** DISPUTED ** Multiple     integer overflows in the lzo1x_decompress_safe function     in lib/lzo/lzo1x_decompress_safe.c in the LZO     decompressor in the Linux kernel before 3.15.2 allow     context-dependent attackers to cause a denial of     service (memory corruption) via a crafted Literal Run.
    NOTE: the author of the LZO algorithms says 'the Linux     kernel is *not* affected media hype.'(CVE-2014-4608)A     certain backport in the TCP Fast Open implementation     for the Linux kernel before 3.18 does not properly     maintain a count value, which allow local users to     cause a denial of service (system crash) via the Fast     Open feature, as demonstrated by visiting the     chrome://flags/#enable-tcp-fast-open URL when using     certain 3.10.x through 3.16.x kernel builds, including     longterm-maintenance releases and ckt (aka Canonical     Kernel Team) builds.(CVE-2015-3332)An elevation of     privilege vulnerability in the kernel scsi driver.
    Product: Android. Versions: Android kernel. Android ID     A-65023233.(CVE-2017-13168)An issue was discovered in     drivers/i2c/i2c-core-smbus.c in the Linux kernel before     4.14.15. There is an out of bounds write in the     function i2c_smbus_xfer_emulated.(CVE-2017-18551)An     issue was discovered in net/ipv6/ip6mr.c in the Linux     kernel before 4.11. By setting a specific socket     option, an attacker can control a pointer in kernel     land and cause an inet_csk_listen_stop general     protection fault, or potentially execute arbitrary code     under certain circumstances. The issue can be triggered     as root (e.g., inside a default LXC container or with     the CAP_NET_ADMIN capability) or after namespace     unsharing. This occurs because sk_type and protocol are     not checked in the appropriate part of the ip6_mroute_*     functions. NOTE: this affects Linux distributions that     use 4.9.x longterm kernels before     4.9.187.(CVE-2017-18509)An issue was discovered in the     Linux kernel before 4.14.11. A double free may be     caused by the function allocate_trace_buffer in the     file kernel/trace/trace.c.(CVE-2017-18595)An issue was     discovered in the Linux kernel through 4.17.10. There     is a NULL pointer dereference and panic in     hfsplus_lookup() in fs/hfsplus/dir.c when opening a     file (that is purportedly a hard link) in an hfs+     filesystem that has malformed catalog data, and is     mounted read-only without a metadata     directory.(CVE-2018-14617)An issue was discovered in     write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in     the Linux kernel through 5.3.2. The cxgb4 driver is     directly calling dma_map_single (a DMA function) from a     stack variable. This could allow an attacker to trigger     a Denial of Service, exploitable if this driver is used     on an architecture for which this stack/DMA interaction     has security relevance.(CVE-2019-17075)Double free     vulnerability in the snd_usbmidi_create function in     sound/usb/midi.c in the Linux kernel before 4.5 allows     physically proximate attackers to cause a denial of     service (panic) or possibly have unspecified other     impact via vectors involving an invalid USB     descriptor.(CVE-2016-2384)fsamespace.c in the Linux     kernel through 3.16.1 does not properly restrict     clearing MNT_NODEV, MNT_NOSUID, and MNT_NOEXEC and     changing MNT_ATIME_MASK during a remount of a bind     mount, which allows local users to gain privileges,     interfere with backups and auditing on systems that had     atime enabled, or cause a denial of service (excessive     filesystem updating) on systems that had atime disabled     via a 'mount -o remount' command within a user     namespace.(CVE-2014-5207)fs/overlayfs/dir.c in the     OverlayFS filesystem implementation in the Linux kernel     before 4.6 does not properly verify the upper dentry     before proceeding with unlink and rename system-call     processing, which allows local users to cause a denial     of service (system crash) via a rename system call that     specifies a self-hardlink.(CVE-2016-6197)In the Linux     kernel before 4.1.4, a buffer overflow occurs when     checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size     for a DiSEqC command is 6, according to the userspace     API. However, the code allows larger values such as     23.(CVE-2015-9289)In the Linux kernel through 5.3.2,     cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c     does not reject a long SSID IE, leading to a Buffer     Overflow.(CVE-2019-17133)Insufficient access control in     the Intel(R) PROSet/Wireless WiFi Software driver     before version 21.10 may allow an unauthenticated user     to potentially enable denial of service via adjacent     access.(CVE-2019-0136)Linux distributions that have not     patched their long-term kernels with     https://git.kernel.org/linus/a87938b2e246b81b4fb713edb3     71a9fa3c5c3c86 (committed on April 14, 2015). This     kernel vulnerability was fixed in April 2015 by commit     a87938b2e246b81b4fb713edb371a9fa3c5c3c86 (backported to     Linux 3.10.77 in May 2015), but it was not recognized     as a security threat. With     CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a     normal top-down address allocation strategy,     load_elf_binary() will attempt to map a PIE binary into     an address range immediately below mm->mmap_base.
    Unfortunately, load_elf_ binary() does not take account     of the need to allocate sufficient space for the entire     binary which means that, while the first PT_LOAD     segment is mapped below mm->mmap_base, the subsequent     PT_LOAD segment(s) end up being mapped above     mm->mmap_base into the are that is supposed to be the     'gap' between the stack and the     binary.(CVE-2017-1000253)Race condition in the     sclp_ctl_ioctl_sccb function in     drivers/s390/char/sclp_ctl.c in the Linux kernel before     4.6 allows local users to obtain sensitive information     from kernel memory by changing a certain length value,     aka a 'double fetch'     vulnerability.(CVE-2016-6130)rtl_p2p_noa_ie in drivers     et/wireless/realtek/rtlwifi/ps.c in the Linux kernel     through 5.3.6 lacks a certain upper-bound check,     leading to a buffer     overflow.(CVE-2019-17666)sound/core/timer.c in the     Linux kernel through 4.6 does not initialize certain r1     data structures, which allows local users to obtain     sensitive information from kernel stack memory via     crafted use of the ALSA timer interface, related to the     (1) snd_timer_user_ccallback and (2)     snd_timer_user_tinterrupt     functions.(CVE-2016-4578)Systems with microprocessors     utilizing speculative execution and branch prediction     may allow unauthorized disclosure of information to an     attacker with local user access via a side-channel     analysis.(CVE-2017-5753)The acm_probe function in     drivers/usb/class/cdc-acm.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (NULL pointer dereference and system     crash) via a USB device without both a control and a     data endpoint descriptor.(CVE-2016-3138)The     arcmsr_iop_message_xfer function in     drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel     through 4.8.2 does not restrict a certain length field,     which allows local users to gain privileges or cause a     denial of service (heap-based buffer overflow) via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control     code.(CVE-2016-7425)The ati_remote2_probe function in     drivers/input/misc/ati_remote2.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2185)The     create_fixed_stream_quirk function in     sound/usb/quirks.c in the snd-usb-audio driver in the     Linux kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (NULL pointer     dereference or double free, and system crash) via a     crafted endpoints value in a USB device     descriptor.(CVE-2016-2184)The digi_port_init function     in drivers/usb/serial/digi_acceleport.c in the Linux     kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (NULL pointer     dereference and system crash) via a crafted endpoints     value in a USB device descriptor.(CVE-2016-3140)The     do_remount function in fsamespace.c in the Linux kernel     through 3.16.1 does not maintain the MNT_LOCK_READONLY     bit across a remount of a bind mount, which allows     local users to bypass an intended read-only restriction     and defeat certain sandbox protection mechanisms via a     'mount -o remount' command within a user     namespace.(CVE-2014-5206)The gtco_probe function in     drivers/input/tablet/gtco.c in the Linux kernel through     4.5.2 allows physically proximate attackers to cause a     denial of service (NULL pointer dereference and system     crash) via a crafted endpoints value in a USB device     descriptor.(CVE-2016-2187)The hub_activate function in     drivers/usb/core/hub.c in the Linux kernel before 4.3.5     does not properly maintain a hub-interface data     structure, which allows physically proximate attackers     to cause a denial of service (invalid memory access and     system crash) or possibly have unspecified other impact     by unplugging a USB hub device.(CVE-2015-8816)The     ims_pcu_parse_cdc_data function in     drivers/input/misc/ims-pcu.c in the Linux kernel before     4.5.1 allows physically proximate attackers to cause a     denial of service (system crash) via a USB device     without both a master and a slave     interface.(CVE-2016-3689)The Linux Kernel running on     AMD64 systems will sometimes map the contents of PIE     executable, the heap or ld.so to where the stack is     mapped allowing attackers to more easily manipulate the     stack. Linux Kernel version 4.11.5 is     affected.(CVE-2017-1000379)The powermate_probe function     in drivers/input/misc/powermate.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2186)The signal     implementation in the Linux kernel before 4.3.5 on     powerpc platforms does not check for an MSR with both     the S and T bits set, which allows local users to cause     a denial of service (TM Bad Thing exception and panic)     via a crafted application.(CVE-2015-8844)The     snd_timer_user_params function in sound/core/timer.c in     the Linux kernel through 4.6 does not initialize a     certain data structure, which allows local users to     obtain sensitive information from kernel stack memory     via crafted use of the ALSA timer     interface.(CVE-2016-4569)The tm_reclaim_thread function     in arch/powerpc/kernel/process.c in the Linux kernel     before 4.4.1 on powerpc platforms does not ensure that     TM suspend mode exists before proceeding with a     tm_reclaim call, which allows local users to cause a     denial of service (TM Bad Thing exception and panic)     via a crafted application.(CVE-2015-8845)The VFS     subsystem in the Linux kernel 3.x provides an     incomplete set of requirements for setattr operations     that underspecifies removing extended privilege     attributes, which allows local users to cause a denial     of service (capability stripping) via a failed     invocation of a system call, as demonstrated by using     chown to remove a capability from the ping or Wireshark     dumpcap program.(CVE-2015-1350)The wacom_probe function     in drivers/input/tablet/wacom_sys.c in the Linux kernel     before 3.17 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-3139)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - In ashmem_ioctl of ashmem.c, there is an out-of-bounds     write due to insufficient locking when accessing asma.
    This could lead to a local elevation of privilege     enabling code execution as a privileged process with no     additional execution privileges needed. User     interaction is not needed for exploitation. Product:
    Android. Versions: Android kernel. Android ID:
    A-66954097.(CVE-2017-13216)

  - A certain backport in the TCP Fast Open implementation     for the Linux kernel before 3.18 does not properly     maintain a count value, which allow local users to     cause a denial of service (system crash) via the Fast     Open feature, as demonstrated by visiting the     chrome://flags/#enable-tcp-fast-open URL when using     certain 3.10.x through 3.16.x kernel builds, including     longterm-maintenance releases and ckt (aka Canonical     Kernel Team) builds.(CVE-2015-3332)

  - The rtnl_fill_link_ifmap function in     net/core/rtnetlink.c in the Linux kernel before 4.5.5     does not initialize a certain data structure, which     allows local users to obtain sensitive information from     kernel stack memory by reading a Netlink     message.(CVE-2016-4486)

  - The ip6gre_err function in net/ipv6/ip6_gre.c in the     Linux kernel allows remote attackers to have     unspecified impact via vectors involving GRE flags in     an IPv6 packet, which trigger an out-of-bounds     access.(CVE-2017-5897)

  - In the Linux kernel before version 4.12, Kerberos 5     tickets decoded when using the RXRPC keys incorrectly     assumes the size of a field.
