Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-5794-1)
Summary:	The remote host is missing an update for the 'linux-aws' package(s) announced via the USN-5794-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux-aws' package(s) announced via the USN-5794-1 advisory. Vulnerability Insight: It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43945) Tamas Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-42896) It was discovered that the Xen netback driver in the Linux kernel did not properly handle packets structured in certain ways. An attacker in a guest VM could possibly use this to cause a denial of service (host NIC availability). (CVE-2022-3643) It was discovered that an integer overflow vulnerability existed in the Bluetooth subsystem in the Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2022-45934) Affected Software/OS: 'linux-aws' package(s) on Ubuntu 16.04. Solution: Please install the updated package(s). CVSS Score: 8.3 CVSS Vector: AV:A/AC:L/Au:N/C:C/I:C/A:C
