Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-6092-1)
Summary:	The remote host is missing an update for the 'linux-azure, linux-azure-4.15' package(s) announced via the USN-6092-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux-azure, linux-azure-4.15' package(s) announced via the USN-6092-1 advisory. Vulnerability Insight: Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-0459) Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel did not properly initialize some data structures. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-1513) 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 NET/ROM protocol implementation in the Linux kernel contained a race condition in some situations, 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-2023-32269) Duoming Zhou discovered that a race condition existed in the infrared receiver/transceiver driver in the Linux kernel, leading to a use-after- free vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-1118) Affected Software/OS: 'linux-azure, linux-azure-4.15' package(s) on Ubuntu 14.04, Ubuntu 16.04, Ubuntu 18.04. 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
