The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3470-1 advisory.

  - The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the     relationship between the minimum fragment length and the maximum packet size, which allows local users to     gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN     capability. (CVE-2016-8632)

  - Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows local users to gain privileges or     cause a denial of service (list corruption or use-after-free) via simultaneous file-descriptor operations     that leverage improper might_cancel queueing. (CVE-2017-10661)

  - The sanity_check_raw_super function in fs/f2fs/super.c in the Linux kernel before 4.11.1 does not validate     the segment count, which allows local users to gain privileges via unspecified vectors. (CVE-2017-10662)

  - The sanity_check_ckpt function in fs/f2fs/super.c in the Linux kernel before 4.12.4 does not validate the     blkoff and segno arrays, which allows local users to gain privileges via unspecified vectors.
    (CVE-2017-10663)

  - 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)

  - The mq_notify function in the Linux kernel through 4.11.9 does not set the sock pointer to NULL upon entry     into the retry logic. During a user-space close of a Netlink socket, it allows attackers to cause a denial     of service (use-after-free) or possibly have unspecified other impact. (CVE-2017-11176)

  - The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h in the Linux kernel before 4.13.2 does not verify     that a filesystem has a realtime device, which allows local users to cause a denial of service (NULL     pointer dereference and OOPS) via vectors related to setting an RHINHERIT flag on a directory.
    (CVE-2017-14340)

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

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0036 advisory.

The remote Oracle Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2017-3659 advisory.

  - A missing authorization check in the fscrypt_process_policy function in fs/crypto/policy.c in the ext4 and     f2fs filesystem encryption support in the Linux kernel before 4.7.4 allows a user to assign an encryption     policy to a directory owned by a different user, potentially creating a denial of service.
    (CVE-2016-10318)

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

The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2018-4071 advisory.

  - The x86/fpu (Floating Point Unit) subsystem in the Linux kernel before 4.13.5, when a processor supports     the xsave feature but not the xsaves feature, does not correctly handle attempts to set reserved bits in     the xstate header via the ptrace() or rt_sigreturn() system call, allowing local users to read the FPU     registers of other processes on the system, related to arch/x86/kernel/fpu/regset.c and     arch/x86/kernel/fpu/signal.c. (CVE-2017-15537)

  - drivers/media/usb/dvb-usb/dib0700_devices.c in the Linux kernel through 4.13.11 allows local users to     cause a denial of service (BUG and system crash) or possibly have unspecified other impact via a crafted     USB device. (CVE-2017-16646)

  - The get_endpoints function in drivers/usb/misc/usbtest.c in the Linux kernel through 4.13.11 allows local     users to cause a denial of service (NULL pointer dereference and system crash) or possibly have     unspecified other impact via a crafted USB device. (CVE-2017-16532)

  - A flaw was found in the Linux 4.x kernel's implementation of 32-bit syscall interface for bridging. This     allowed a privileged user to arbitrarily write to a limited range of kernel memory. (CVE-2018-1068)

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

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

  - CVE-2017-7518     Andy Lutomirski discovered that KVM is prone to an     incorrect debug exception (#DB) error occurring while     emulating a syscall instruction. A process inside a     guest can take advantage of this flaw for privilege     escalation inside a guest.

  - CVE-2017-7558 (stretch only)     Stefano Brivio of Red Hat discovered that the SCTP     subsystem is prone to a data leak vulnerability due to     an out-of-bounds read flaw, allowing to leak up to 100     uninitialized bytes to userspace.

  - CVE-2017-10661 (jessie only)     Dmitry Vyukov of Google reported that the timerfd     facility does not properly handle certain concurrent     operations on a single file descriptor. This allows a     local attacker to cause a denial of service or     potentially execute arbitrary code.

  - CVE-2017-11600     Bo Zhang reported that the xfrm subsystem does not     properly validate one of the parameters to a netlink     message. Local users with the CAP_NET_ADMIN capability     can use this to cause a denial of service or potentially     to execute arbitrary code.

  - CVE-2017-12134 / #866511 / XSA-229     Jan H. Schoenherr of Amazon discovered that when Linux     is running in a Xen PV domain on an x86 system, it may     incorrectly merge block I/O requests. A buggy or     malicious guest may trigger this bug in dom0 or a PV     driver domain, causing a denial of service or     potentially execution of arbitrary code.

  This issue can be mitigated by disabling merges on the underlying   back-end block devices, e.g.:echo 2 >   /sys/block/nvme0n1/queue/nomerges

  - CVE-2017-12146 (stretch only)     Adrian Salido of Google reported a race condition in     access to the'driver_override' attribute for platform     devices in sysfs. If unprivileged users are permitted to     access this attribute, this might allow them to gain     privileges.

  - CVE-2017-12153     Bo Zhang reported that the cfg80211 (wifi) subsystem     does not properly validate the parameters to a netlink     message. Local users with the CAP_NET_ADMIN capability     (in any user namespace with a wifi device) can use this     to cause a denial of service.

  - CVE-2017-12154     Jim Mattson of Google reported that the KVM     implementation for Intel x86 processors did not     correctly handle certain nested hypervisor     configurations. A malicious guest (or nested guest in a     suitable L1 hypervisor) could use this for denial of     service.

  - CVE-2017-14106     Andrey Konovalov discovered that a user-triggerable     division by zero in the tcp_disconnect() function could     result in local denial of service.

  - CVE-2017-14140     Otto Ebeling reported that the move_pages() system call     performed insufficient validation of the UIDs of the     calling and target processes, resulting in a partial     ASLR bypass. This made it easier for local users to     exploit vulnerabilities in programs installed with the     set-UID permission bit set.

  - CVE-2017-14156     'sohu0106' reported an information leak in the atyfb     video driver. A local user with access to a framebuffer     device handled by this driver could use this to obtain     sensitive information.

  - CVE-2017-14340     Richard Wareing discovered that the XFS implementation     allows the creation of files with the 'realtime' flag on     a filesystem with no realtime device, which can result     in a crash (oops). A local user with access to an XFS     filesystem that does not have a realtime device can use     this for denial of service.

  - CVE-2017-14489     ChunYu Wang of Red Hat discovered that the iSCSI     subsystem does not properly validate the length of a     netlink message, leading to memory corruption. A local     user with permission to manage iSCSI devices can use     this for denial of service or possibly to execute     arbitrary code.

  - CVE-2017-14497 (stretch only)     Benjamin Poirier of SUSE reported that vnet headers are     not properly handled within the tpacket_rcv() function     in the raw packet (af_packet) feature. A local user with     the CAP_NET_RAW capability can take advantage of this     flaw to cause a denial of service (buffer overflow, and     disk and memory corruption) or have other impact.

  - CVE-2017-1000111     Andrey Konovalov of Google reported a race condition in     the raw packet (af_packet) feature. Local users with the     CAP_NET_RAW capability can use this for denial of     service or possibly to execute arbitrary code.

  - CVE-2017-1000112     Andrey Konovalov of Google reported a race condition     flaw in the UDP Fragmentation Offload (UFO) code. A     local user can use this flaw for denial of service or     possibly to execute arbitrary code.

  - CVE-2017-1000251 / #875881     Armis Labs discovered that the Bluetooth subsystem does     not properly validate L2CAP configuration responses,     leading to a stack-based buffer overflow. This is one of     several vulnerabilities dubbed 'Blueborne'. A nearby     attacker can use this to cause a denial of service or     possibly to execute arbitrary code on a system with     Bluetooth enabled.

  - CVE-2017-1000252 (stretch only)     Jan H. Schoenherr of Amazon reported that the KVM     implementation for Intel x86 processors did not     correctly validate interrupt injection requests. A local     user with permission to use KVM could use this for     denial of service.

  - CVE-2017-1000370     The Qualys Research Labs reported that a large argument     or environment list can result in ASLR bypass for 32-bit     PIE binaries.

  - CVE-2017-1000371     The Qualys Research Labs reported that a large argument     or environment list can result in a stack/heap clash for     32-bit PIE binaries.

  - CVE-2017-1000380     Alexander Potapenko of Google reported a race condition     in the ALSA (sound) timer driver, leading to an     information leak. A local user with permission to access     sound devices could use this to obtain sensitive     information.

Debian disables unprivileged user namespaces by default, but if they are enabled (via the kernel.unprivileged_userns_clone sysctl) then CVE-2017-11600, CVE-2017-14497 and CVE-2017-1000111 can be exploited by any local user.
