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 MAIN 6.01, has kernel packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in the Linux kernel's NFS     implementation, all versions 3.x and all versions 4.x up     to 4.20. An attacker, who is able to mount an exported     NFS filesystem, is able to trigger a null pointer     dereference by using an invalid NFS sequence. This can     panic the machine and deny access to the NFS server. Any     outstanding disk writes to the NFS server will be lost.
    (CVE-2018-16871)

  - ieee802154_create in net/ieee802154/socket.c in the     AF_IEEE802154 network module in the Linux kernel through     5.3.2 does not enforce CAP_NET_RAW, which means that     unprivileged users can create a raw socket, aka     CID-e69dbd4619e7. (CVE-2019-17053)

  - base_sock_create in drivers/isdn/mISDN/socket.c in the     AF_ISDN network module in the Linux kernel through 5.3.2     does not enforce CAP_NET_RAW, which means that     unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21. (CVE-2019-17055)

  - The flow_dissector feature in the Linux kernel 4.3     through 5.x before 5.3.10 has a device tracking     vulnerability, aka CID-55667441c84f. This occurs because     the auto flowlabel of a UDP IPv6 packet relies on a     32-bit hashrnd value as a secret, and because jhash     (instead of siphash) is used. The hashrnd value remains     the same starting from boot time, and can be inferred by     an attacker. This affects net/core/flow_dissector.c and     related code. (CVE-2019-18282)

  - An issue was discovered in net/ipv4/sysctl_net_ipv4.c in     the Linux kernel before 5.0.11. There is a     net/ipv4/tcp_input.c signed integer overflow in     tcp_ack_update_rtt() when userspace writes a very large     integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading     to a denial of service or possibly unspecified other     impact, aka CID-19fad20d15a6. (CVE-2019-18805)

  - A memory leak in the mlx5_fpga_conn_create_cq() function     in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c     in the Linux kernel before 5.3.11 allows attackers to     cause a denial of service (memory consumption) by     triggering mlx5_vector2eqn() failures, aka     CID-c8c2a057fdc7. (CVE-2019-19045)

  - ** DISPUTED ** A memory leak in the     nl80211_get_ftm_responder_stats() function in     net/wireless/nl80211.c in the Linux kernel through     5.3.11 allows attackers to cause a denial of service     (memory consumption) by triggering nl80211hdr_put()     failures, aka CID-1399c59fa929. NOTE: third parties     dispute the relevance of this because it occurs on a     code path where a successful allocation has already     occurred. (CVE-2019-19055)

  - A memory leak in the bnxt_re_create_srq() function in     drivers/infiniband/hw/bnxt_re/ib_verbs.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial     of service (memory consumption) by triggering copy to     udata failures, aka CID-4a9d46a9fe14. (CVE-2019-19077)

  - In the Linux kernel before 5.3.9, there are multiple     out-of-bounds write bugs that can be caused by a     malicious USB device in the Linux kernel HID drivers,     aka CID-d9d4b1e46d95. This affects drivers/hid/hid-     axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c,     drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c,     drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-     microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-     tmff.c, and drivers/hid/hid-zpff.c. (CVE-2019-19532)

  - In the Linux kernel before 5.3.11, there is an info-leak     bug that can be caused by a malicious USB device in the     drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka     CID-f7a1337f0d29. (CVE-2019-19534)

  - In the Linux kernel 5.4.0-rc2, there is a use-after-free     (read) in the __blk_add_trace function in     kernel/trace/blktrace.c (which is used to fill out a     blk_io_trace structure and place it in a per-cpu sub-     buffer). (CVE-2019-19768)

  - A memory leak in the kernel_read_file function in     fs/exec.c in the Linux kernel through 4.20.11 allows     attackers to cause a denial of service (memory     consumption) by triggering vfs_read failures.
    (CVE-2019-8980)

  - 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)

  - In the Linux kernel through 5.6.7 on the s390 platform,     code execution may occur because of a race condition, as     demonstrated by code in enable_sacf_uaccess in     arch/s390/lib/uaccess.c that fails to protect against a     concurrent page table upgrade, aka CID-3f777e19d171. A     crash could also occur. (CVE-2020-11884)

  - An issue was discovered in the Linux kernel before     5.6.5. There is a use-after-free in block/bfq-iosched.c     related to bfq_idle_slice_timer_body. (CVE-2020-12657)

  - A flaw was discovered in the way that the KVM hypervisor     handled instruction emulation for an L2 guest when     nested virtualisation is enabled. Under some     circumstances, an L2 guest may trick the L0 guest into     accessing sensitive L1 resources that should be     inaccessible to the L2 guest. (CVE-2020-2732)

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

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 ** In     kernel/compat.c in the Linux kernel before 3.17, as     used in Google Chrome OS and other products, there is a     possible out-of-bounds read. restart_syscall uses     uninitialized data when restarting     compat_sys_nanosleep. NOTE: this is disputed because     the code path is unreachable.(CVE-2014-3180)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)A heap-based buffer overflow     vulnerability was found in the Linux kernel, version     kernel-2.6.32, in Marvell WiFi chip driver. A remote     attacker could cause a denial of service (system crash)     or, possibly execute arbitrary code, when the     lbs_ibss_join_existing function is called after a STA     connects to an AP.(CVE-2019-14896)A memory leak in the     ath10k_usb_hif_tx_sg() function in drivers/     net/wireless/ath/ath10k/usb.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of     service (memory consumption) by triggering     usb_submit_urb() failures, aka     CID-b8d17e7d93d2.(CVE-2019-19078)A memory leak in the     mlx5_fpga_conn_create_cq() function in drivers/     net/ethernet/mellanox/mlx5/core/fpga/conn.c in the     Linux kernel before 5.3.11 allows attackers to cause a     denial of service (memory consumption) by triggering     mlx5_vector2eqn() failures, aka     CID-c8c2a057fdc7.(CVE-2019-19045)A stack-based buffer     overflow was found in the Linux kernel, version     kernel-2.6.32, in Marvell WiFi chip driver. An attacker     is able to cause a denial of service (system crash) or,     possibly execute arbitrary code, when a STA works in     IBSS mode (allows connecting stations together without     the use of an AP) and connects to another     STA.(CVE-2019-14897)An out-of-bounds memory write issue     was found in the Linux Kernel, version 3.13 through     5.4, in the way the Linux kernel's KVM hypervisor     handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request     to get CPUID features emulated by the KVM hypervisor. A     user or process able to access the '/dev/kvm' device     could use this flaw to crash the system, resulting in a     denial of service.(CVE-2019-19332)Improper invalidation     for page table updates by a virtual guest operating     system for multiple Intel(R) Processors may allow an     authenticated user to potentially enable denial of     service of the host system via local     access.(CVE-2018-12207)In the Android kernel in the     video driver there is a use after free due to a race     condition. This could lead to local escalation of     privilege with no additional execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2019-9458)In the AppleTalk subsystem     in the Linux kernel before 5.1, there is a potential     NULL pointer dereference because register_snap_client     may return NULL. This will lead to denial of service in     net/appletalk/aarp.c and net/appletalk/ddp.c, as     demonstrated by unregister_snap_client, aka     CID-9804501fa122.(CVE-2019-19227)In the Linux kernel     5.0.21, mounting a crafted btrfs filesystem image,     performing some operations, and then making a syncfs     system call can lead to a use-after-free in

(In other words,     although this slice expiration would typically be seen     with benign workloads, it is possible that an attacker     could calculate how many stray requests are required to     force an entire Kubernetes cluster into a     low-performance state caused by slice expiration, and     ensure that a DDoS attack sent that number of stray     requests. An attack does not affect the stability of     the kernel it only causes mismanagement of application     execution.)(CVE-2019-19922)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     pcpu_embed_first_chunk function in mm/percpu.c in the     Linux kernel through 4.14.14 allows local users to     obtain sensitive address information by reading dmesg     data from a 'pages/cpu' printk call.(CVE-2018-5995)TSX     Asynchronous Abort condition on some CPUs utilizing     speculative execution may allow an authenticated user     to potentially enable information disclosure via a side     channel with local access.(CVE-2019-11135)An issue was     discovered in drivers/scsi/aacraid/commctrl.c in the     Linux kernel before 4.13. There is potential exposure     of kernel stack memory because aac_send_raw_srb does     not initialize the reply structure.(CVE-2017-18549)An     issue was discovered in drivers/scsi/aacraid/commctrl.c     in the Linux kernel before 4.13. There is potential     exposure of kernel stack memory because     aac_get_hba_info does not initialize the hbainfo     structure.(CVE-2017-18550)In the Linux kernel through     4.15.4, the floppy driver reveals the addresses of     kernel functions and global variables using printk     calls within the function show_floppy in     drivers/block/floppy.c. An attacker can read this     information from dmesg and use the addresses to find     the locations of kernel code and data and bypass kernel     security protections such as KASLR.(CVE-2018-7273)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 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)In the     Linux kernel 5.0.21, mounting a crafted ext4 filesystem     image, performing some operations, and unmounting can     lead to a use-after-free in ext4_put_super in     fs/ext4/super.c, related to dump_orphan_list in     fs/ext4/super.c.(CVE-2019-19447)In the Linux kernel     through 5.4.6, there is a NULL pointer dereference in     drivers/scsi/libsas/sas_discover.c because of     mishandling of port disconnection during discovery,     related to a PHY down race condition, aka     CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel     before 5.1.6, there is a use-after-free in cpia2_exit()     in drivers/media/usb/cpia2/cpia2_v4l.c that will cause     denial of service, aka     CID-dea37a972655.(CVE-2019-19966)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)mwifiex_tm_cmd in drivers/     net/wireless/marvell/mwifiex/cfg80211.c in the Linux     kernel before 5.1.6 has some error-handling cases that     did not free allocated hostcmd memory, aka     CID-003b686ace82. This will cause a memory leak and     denial of service.(CVE-2019-20095)
