Ubuntu 16.04 ESM : Linux kernel vulnerabilities (USN-6254-1)

critical Nessus Plugin ID 178912

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-6254-1 advisory.

 Jordy Zomer and Alexandra Sandulescu discovered that syscalls invoking the do_prlimit() function in the Linux kernel did not properly handle speculative execution barriers. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-0458)

 It was discovered that a race condition existed in the btrfs file system implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-1611)

 It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). (CVE-2023-2124)

 It was discovered that a use-after-free vulnerability existed in the iSCSI TCP implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash).
 (CVE-2023-2162)

 It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle extra inode size for extended attributes, leading to a use-after-free vulnerability. A privileged attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code.
 (CVE-2023-2513)

 It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3090)

 It was discovered that the Ricoh R5C592 MemoryStick card reader driver in the Linux kernel contained a race condition during module unload, leading to 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-2023-3141)

 It was discovered that a use-after-free vulnerability existed in the IEEE 1394 (Firewire) implementation in the Linux kernel. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3159)

 Sanan Hasanov discovered that the framebuffer console driver in the Linux kernel did not properly perform checks for font dimension limits. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-3161)

 It was discovered that the kernel->user space relay implementation in the Linux kernel did not properly perform certain buffer calculations, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2023-3268)

 It was discovered that the netfilter subsystem in the Linux kernel did not properly handle some error conditions, leading to 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-2023-3390)

 Tanguy Dubroca discovered that the netfilter subsystem in the Linux kernel did not properly handle certain pointer data type, leading to an out-of- bounds write vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35001)

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.
