Ubuntu 16.04 ESM : Linux kernel vulnerabilities (USN-5650-1)

high Nessus Plugin ID 165602

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5650-1 advisory.

 It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33655)

 It was discovered that the virtual terminal driver in the Linux kernel did not properly handle VGA console font changes, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33656)

 Christian Brauner discovered that the XFS file system implementation in the Linux kernel did not properly handle setgid file creation. A local attacker could use this to gain elevated privileges. (CVE-2021-4037)

 It was discovered that the ext4 file system implementation in the Linux kernel did not properly initialize memory in some situations. A privileged local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0850)

 Duoming Zhou discovered that the AX.25 amateur radio protocol implementation in the Linux kernel did not handle detach events properly in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1199)

 Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux kernel during device detach operations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1204)

 Norbert Slusarek discovered that a race condition existed in the perf subsystem in the Linux kernel, resulting in a use-after-free vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1729)

 It was discovered that the Packet network protocol implementation in the Linux kernel contained an out-of- bounds access. A remote attacker could use this to expose sensitive information (kernel memory).
 (CVE-2022-20368)

 It was discovered that the Open vSwitch implementation in the Linux kernel contained an out of bounds write vulnerability in certain situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-2639)

 Jann Horn discovered that the ASIX AX88179/178A USB Ethernet driver in the Linux kernel contained multiple out-of-bounds vulnerabilities. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-2964)

 Hao Sun and Jiacheng Xu discovered that the NILFS file system implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-2978)

 Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2022-3028)

 It was discovered that the Journaled File System (JFS) in the Linux kernel contained a null pointer dereference in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3202)

 Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter subsystem in the Linux kernel did not properly handle rules that truncated packets below the packet header size. When such rules are in place, a remote attacker could possibly use this to cause a denial of service (system crash).
 (CVE-2022-36946)

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

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

Solution

Update the affected kernel package.
