Test ID:	1.3.6.1.4.1.25623.1.1.12.2023.6343.1
Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-6343-1)
Summary:	The remote host is missing an update for the 'linux-oem-6.1' package(s) announced via the USN-6343-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux-oem-6.1' package(s) announced via the USN-6343-1 advisory. Vulnerability Insight: It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service (excessive CPU consumption). (CVE-2023-1206) Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service (host system crash) or possibly execute arbitrary code. (CVE-2023-34319) It was discovered that the bluetooth subsystem in the Linux kernel did not properly handle L2CAP socket release, 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-2023-40283) It was discovered that some network classifier implementations in the Linux kernel contained use-after-free vulnerabilities. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4128) Andy Nguyen discovered that the KVM implementation for AMD processors in the Linux kernel with Secure Encrypted Virtualization (SEV) contained a race condition when accessing the GHCB page. A local attacker in a SEV guest VM could possibly use this to cause a denial of service (host system crash). (CVE-2023-4155) It was discovered that the TUN/TAP driver in the Linux kernel did not properly initialize socket data. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-4194) Maxim Suhanov discovered that the exFAT file system implementation in the Linux kernel did not properly check a file name length, leading to an out- of-bounds write vulnerability. An attacker could use this to construct a malicious exFAT image that, when mounted and operated on, could cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4273) Affected Software/OS: 'linux-oem-6.1' package(s) on Ubuntu 22.04. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:L/AC:L/Au:S/C:C/I:C/A:C
