USN-5801-1: Vim vulnerabilities It was discovered that Vim makes illegal memory calls when pasting brackets in Ex mode. An attacker could possibly use this to crash Vim, access or modify memory, or execute arbitrary commands. This issue affected only Ubuntu 20.04 and 22.04 (CVE-2022-0392) It was discovered that Vim makes illegal memory calls when making certain retab calls. An attacker could possibly use this to crash Vim, access or modify memory, or execute arbitrary commands. (CVE-2022-0417) Source: USN-5801-1: Vim vulnerabilities

USN-5802-1: Linux kernel vulnerabilities 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) Tamás 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 [ more… ]
