Memory leak in the virtio_gpu_object_create function in drivers/gpu/drm/virtio/virtgpu_object.c in the Linux kernel through 4.11.8 allows attackers to cause a denial of service (memory consumption) by triggering object-initialization failures.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: out of bounds read in drivers/media/usb/dvb-usb/technisat-usb2.c (CVE-2019-15505)

  - kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

  - block/scsi_ioctl.c in the Linux kernel through 3.8 does not properly consider the SCSI device class during     authorization of SCSI commands, which allows local users to bypass intended access restrictions via an     SG_IO ioctl call that leverages overlapping opcodes. (CVE-2012-4542)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - A double free vulnerability was found in netlink_dump,     which could cause a denial of service or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9806i1/4%0

  - Memory leak in drivers/media/video/videobuf-core.c in     the videobuf subsystem in the Linux kernel 2.6.x     through 4.x allows local users to cause a denial of     service (memory consumption) by leveraging /dev/video     access for a series of mmap calls that require new     allocations, a different vulnerability than     CVE-2007-6761. NOTE: as of 2016-06-18, this affects     only 11 drivers that have not been updated to use     videobuf2 instead of videobuf.(CVE-2010-5321i1/4%0

  - ** RESERVED ** This candidate has been reserved by an     organization or individual that will use it when     announcing a new security problem. When the candidate     has been publicized, the details for this candidate     will be provided.(CVE-2018-1108i1/4%0

  - drivers/hid/hid-ntrig.c in the Human Interface Device     (HID) subsystem in the Linux kernel through 3.11, when     CONFIG_HID_NTRIG is enabled, allows physically     proximate attackers to cause a denial of service (NULL     pointer dereference and OOPS) via a crafted     device.(CVE-2013-2896i1/4%0

  - 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-2016-3139i1/4%0

  - An integer overflow vulnerability in     ip6_find_1stfragopt() function was found. A local     attacker that has privileges (of CAP_NET_RAW) to open     raw socket can cause an infinite loop inside the     ip6_find_1stfragopt() function.(CVE-2017-7542i1/4%0

  - Memory leak in the virtio_gpu_object_create function in     drivers/gpu/drm/virtio/virtgpu_object.c in the Linux     kernel through 4.11.8 allows attackers to cause a     denial of service (memory consumption) by triggering     object-initialization failures.(CVE-2017-10810i1/4%0

  - The ping_recvmsg function in net/ipv4/ping.c in the     Linux kernel before 3.12.4 does not properly interact     with read system calls on ping sockets, which allows     local users to cause a denial of service (NULL pointer     dereference and system crash) by leveraging unspecified     privileges to execute a crafted     application.(CVE-2013-6432i1/4%0

  - The madvise_willneed function in the Linux kernel     allows local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping.(CVE-2017-18208i1/4%0

  - An issue was discovered in the Linux kernel through     4.18.8. The vmacache_flush_all function in     mm/vmacache.c mishandles sequence number overflows. An     attacker can trigger a use-after-free (and possibly     gain privileges) via certain thread creation, map,     unmap, invalidation, and dereference     operations.(CVE-2018-17182i1/4%0

  - The ieee80211_radiotap_iterator_init function in     net/wireless/radiotap.c in the Linux kernel before     3.11.7 does not check whether a frame contains any data     outside of the header, which might allow attackers to     cause a denial of service (buffer over-read) via a     crafted header.(CVE-2013-7027i1/4%0

  - The Btrfs implementation in the Linux kernel before     3.19 does not ensure that the visible xattr state is     consistent with a requested replacement, which allows     local users to bypass intended ACL settings and gain     privileges via standard filesystem operations (1)     during an xattr-replacement time window, related to a     race condition, or (2) after an xattr-replacement     attempt that fails because the data does not     fit.(CVE-2014-9710i1/4%0

  - A flaw was found in the way the Linux kernel's Stream     Control Transmission Protocol (SCTP) implementation     handled duplicate Address Configuration Change Chunks     (ASCONF). A remote attacker could use either of these     flaws to crash the system.(CVE-2014-3687i1/4%0

  - A syntax vulnerability was discovered in the kernel's     ASN1.1 DER decoder, which could lead to memory     corruption or a complete local denial of service     through x509 certificate DER files. A local system user     could use a specially created key file to trigger     BUG_ON() in the public_key_verify_signature() function     (crypto/asymmetric_keys/public_key.c), to cause a     kernel panic and crash the system.(CVE-2016-2053i1/4%0

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invept     (Invalidate Translations Derived from EPT)     instructions. On hosts with an Intel processor and     invept VM exit support, an unprivileged guest user     could use these instructions to crash the     guest.(CVE-2014-3645i1/4%0

  - The packet_recvmsg function in net/packet/af_packet.c     in the Linux kernel before 3.12.4 updates a certain     length value before ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7270i1/4%0

  - The init_new_context function in     arch/x86/include/asm/mmu_context.h in the Linux kernel,     before 4.12.10, does not correctly handle errors from     LDT table allocation when forking a new process. This     could allow a local attacker to achieve a     use-after-free or possibly have unspecified other     impact by running a specially crafted     program.(CVE-2017-17053i1/4%0

  - It was found that the sanity_check_raw_super() function     in 'fs/f2fs/super.c' file in the Linux kernel before     version 4.12-rc1 does not validate the f2fs filesystem     segment count. This allows an unprivileged local user     to cause a system panic and DoS. Due to the nature of     the flaw, privilege escalation cannot be fully ruled     out, although we believe it is     unlikely.(CVE-2017-10662i1/4%0

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 Virtualization installation on the remote host is affected by the following vulnerabilities :

  - An integer overflow vulnerability was found in the     ring_buffer_resize() calculations in which a privileged     user can adjust the size of the ringbuffer message     size. These calculations can create an issue where the     kernel memory allocator will not allocate the correct     count of pages yet expect them to be usable. This can     lead to the ftrace() output to appear to corrupt kernel     memory and possibly be used for privileged escalation     or more likely kernel panic.(CVE-2016-9754)

  - A flaw was found in the Linux kernel's implementation     of setsockopt for the SO_{SND|RCV}BUFFORCE setsockopt()     system call. Users with non-namespace CAP_NET_ADMIN are     able to trigger this call and create a situation in     which the sockets sendbuff data size could be negative.
    This could adversely affect memory allocations and     create situations where the system could crash or cause     memory corruption.(CVE-2016-9793)

  - A use-after-free vulnerability was found in ALSA pcm     layer, which allows local users to cause a denial of     service, memory corruption, or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9794)

  - A double free vulnerability was found in netlink_dump,     which could cause a denial of service or possibly other     unspecified impact. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-9806)

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets are     implemented in the Linux kernel networking subsystem     handling synchronization. A local user able to open a     raw packet socket (requires the CAP_NET_RAW capability)     can use this issue to crash the     system.(CVE-2017-1000111)

  - An exploitable memory corruption flaw was found in the     Linux kernel. The append path can be erroneously     switched from UFO to non-UFO in ip_ufo_append_data()     when building an UFO packet with MSG_MORE option. If     unprivileged user namespaces are available, this flaw     can be exploited to gain root     privileges.(CVE-2017-1000112)

  - A stack buffer overflow flaw was found in the way the     Bluetooth subsystem of the Linux kernel processed     pending L2CAP configuration responses from a client. On     systems with the stack protection feature enabled in     the kernel (CONFIG_CC_STACKPROTECTOR=y, which is     enabled on all architectures other than s390x and     ppc64le), an unauthenticated attacker able to initiate     a connection to a system via Bluetooth could use this     flaw to crash the system. Due to the nature of the     stack protection feature, code execution cannot be     fully ruled out, although we believe it is unlikely. On     systems without the stack protection feature (ppc64le     the Bluetooth modules are not built on s390x), an     unauthenticated attacker able to initiate a connection     to a system via Bluetooth could use this flaw to     remotely execute arbitrary code on the system with ring     0 (kernel) privileges.(CVE-2017-1000251)

  - A reachable assertion failure flaw was found in the     Linux kernel built with KVM virtualisation(CONFIG_KVM)     support with Virtual Function I/O feature (CONFIG_VFIO)     enabled. This failure could occur if a malicious guest     device sent a virtual interrupt (guest IRQ) with a     larger (i1/4z1024) index value.(CVE-2017-1000252)

  - A flaw was found in the way memory was being allocated     on the stack for user space binaries. If heap (or     different memory region) and stack memory regions were     adjacent to each other, an attacker could use this flaw     to jump over the stack guard gap, cause controlled     memory corruption on process stack or the adjacent     memory region, and thus increase their privileges on     the system. This is a kernel-side mitigation which     increases the stack guard gap size from one page to 1     MiB to make successful exploitation of this issue more     difficult.(CVE-2017-1000364)

  - The Linux Kernel imposes a size restriction on the     arguments and environmental strings passed through     RLIMIT_STACK/RLIMIT_INFINITY, but does not take the     argument and environment pointers into account, which     allows attackers to bypass this     limitation.(CVE-2017-1000365)

  - The offset2lib patch as used in the Linux Kernel     contains a vulnerability that allows a PIE binary to be     execve()'ed with 1GB of arguments or environmental     strings then the stack occupies the address 0x80000000     and the PIE binary is mapped above 0x40000000     nullifying the protection of the offset2lib patch. This     affects Linux Kernel version 4.11.5 and earlier. This     is a different issue than CVE-2017-1000371. This issue     appears to be limited to i386 based     systems.(CVE-2017-1000370)

  - A flaw was found in the processing of incoming L2CAP     bluetooth commands. Uninitialized stack variables can     be sent to an attacker leaking data in kernel address     space.(CVE-2017-1000410)

  - A race condition was found in the Linux kernel before     version 4.11-rc1 in 'fs/timerfd.c' file which allows a     local user to cause a kernel list corruption or     use-after-free via simultaneous operations with a file     descriptor which leverage improper 'might_cancel'     queuing. An unprivileged local user could use this flaw     to cause a denial of service of the system. Due to the     nature of the flaw, privilege escalation cannot be     fully ruled out, although we believe it is     unlikely.(CVE-2017-10661)

  - Memory leak in the virtio_gpu_object_create function in     drivers/gpu/drm/virtio/virtgpu_object.c in the Linux     kernel through 4.11.8 allows attackers to cause a     denial of service (memory consumption) by triggering     object-initialization failures.(CVE-2017-10810)

  - The make_response function in     drivers/block/xen-blkback/blkback.c in the Linux kernel     before 4.11.8 allows guest OS users to obtain sensitive     information from host OS (or other guest OS) kernel     memory by leveraging the copying of uninitialized     padding fields in Xen block-interface response     structures, aka XSA-216.(CVE-2017-10911)

  - A use-after-free flaw was found in the Netlink     functionality of the Linux kernel networking subsystem.
    Due to the insufficient cleanup in the mq_notify     function, a local attacker could potentially use this     flaw to escalate their privileges on the     system.(CVE-2017-11176)

  - Buffer overflow in the mp_override_legacy_irq()     function in arch/x86/kernel/acpi/boot.c in the Linux     kernel through 4.12.2 allows local users to gain     privileges via a crafted ACPI table.(CVE-2017-11473)

  - The xfrm_migrate() function in the     net/xfrm/xfrm_policy.c file in the Linux kernel built     with CONFIG_XFRM_MIGRATE does not verify if the dir     parameter is less than XFRM_POLICY_MAX. This allows a     local attacker to cause a denial of service     (out-of-bounds access) or possibly have unspecified     other impact by sending a XFRM_MSG_MIGRATE netlink     message. This flaw is present in the Linux kernel since     an introduction of XFRM_MSG_MIGRATE in 2.6.21-rc1, up     to 4.13-rc3.(CVE-2017-11600)

  - A security flaw was discovered in     nl80211_set_rekey_data() function in the Linux kernel     since v3.1-rc1 through v4.13. This function does not     check whether the required attributes are present in a     netlink request. This request can be issued by a user     with CAP_NET_ADMIN privilege and may result in NULL     dereference and a system crash.(CVE-2017-12153)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization (nVMX) feature     enabled (nested=1), is vulnerable to a crash due to     disabled external interrupts. As L2 guest could access     (r/w) hardware CR8 register of the host(L0). In a     nested visualization setup, L2 guest user could use     this flaw to potentially crash the host(L0) resulting     in DoS.(CVE-2017-12154)

  - The Linux kernel built with the KVM visualization     support (CONFIG_KVM), with nested visualization(nVMX)     feature enabled (nested=1), was vulnerable to a stack     buffer overflow issue. The vulnerability could occur     while traversing guest page table entries to resolve     guest virtual address(gva). An L1 guest could use this     flaw to crash the host kernel resulting in denial of     service (DoS) or potentially execute arbitrary code on     the host to gain privileges on the     system.(CVE-2017-12188)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

  - CVE-2017-7346     Li Qiang discovered that the DRM driver for VMware     virtual GPUs does not properly check user-controlled     values in the vmw_surface_define_ioctl() functions for     upper limits. A local user can take advantage of this     flaw to cause a denial of service.

  - CVE-2017-7482     Shi Lei discovered that RxRPC Kerberos 5 ticket handling     code does not properly verify metadata, leading to     information disclosure, denial of service or potentially     execution of arbitrary code.

  - CVE-2017-7533     Fan Wu and Shixiong Zhao discovered a race condition     between inotify events and VFS rename operations     allowing an unprivileged local attacker to cause a     denial of service or escalate privileges.

  - CVE-2017-7541     A buffer overflow flaw in the Broadcom IEEE802.11n PCIe     SoftMAC WLAN driver could allow a local user to cause     kernel memory corruption, leading to a denial of service     or potentially privilege escalation.

  - CVE-2017-7542     An integer overflow vulnerability in the     ip6_find_1stfragopt() function was found allowing a     local attacker with privileges to open raw sockets to     cause a denial of service.

  - CVE-2017-9605     Murray McAllister discovered that the DRM driver for     VMware virtual GPUs does not properly initialize memory,     potentially allowing a local attacker to obtain     sensitive information from uninitialized kernel memory     via a crafted ioctl call.

  - CVE-2017-10810     Li Qiang discovered a memory leak flaw within the VirtIO     GPU driver resulting in denial of service (memory     consumption).

  - CVE-2017-10911 / XSA-216     Anthony Perard of Citrix discovered an information leak     flaw in Xen blkif response handling, allowing a     malicious unprivileged guest to obtain sensitive     information from the host or other guests.

  - CVE-2017-11176     It was discovered that the mq_notify() function does not     set the sock pointer to NULL upon entry into the retry     logic. An attacker can take advantage of this flaw     during a user-space close of a Netlink socket to cause a     denial of service or potentially cause other impact.

  - CVE-2017-1000365     It was discovered that argument and environment pointers     are not taken properly into account to the imposed size     restrictions on arguments and environmental strings     passed through RLIMIT_STACK/RLIMIT_INFINITY. A local     attacker can take advantage of this flaw in conjunction     with other flaws to execute arbitrary code.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3378-2 advisory.

  - The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through     RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but does not take the argument and environment pointers into     account, which allows attackers to bypass this limitation. This affects Linux Kernel versions 4.11.5 and     earlier. It appears that this feature was introduced in the Linux Kernel version 2.6.23.
    (CVE-2017-1000365)

  - Memory leak in the virtio_gpu_object_create function in drivers/gpu/drm/virtio/virtgpu_object.c in the     Linux kernel through 4.11.8 allows attackers to cause a denial of service (memory consumption) by     triggering object-initialization failures. (CVE-2017-10810)

  - In the Linux kernel before version 4.12, Kerberos 5 tickets decoded when using the RXRPC keys incorrectly     assumes the size of a field. This could lead to the size-remaining variable wrapping and the data pointer     going over the end of the buffer. This could possibly lead to memory corruption and possible privilege     escalation. (CVE-2017-7482)

  - Race condition in the fsnotify implementation in the Linux kernel through 4.12.4 allows local users to     gain privileges or cause a denial of service (memory corruption) via a crafted application that leverages     simultaneous execution of the inotify_handle_event and vfs_rename functions. (CVE-2017-7533)
