USN-5829-1: Linux kernel (Raspberry Pi) 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 [ more… ]

USN-5828-1: Kerberos vulnerabilities It was discovered that Kerberos incorrectly handled certain S4U2Self requests. An attacker could possibly use this issue to cause a denial of service. This issue was only addressed in Ubuntu 16.04 ESM and Ubuntu 18.04 LTS. (CVE-2018-20217) Greg Hudson discovered that Kerberos PAC implementation incorrectly handled certain parsing operations. A remote attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2022-42898) Source: USN-5828-1: Kerberos vulnerabilities

USN-5827-1: Bind vulnerabilities Rob Schulhof discovered that Bind incorrectly handled a large number of UPDATE messages. A remote attacker could possibly use this issue to cause Bind to consume resources, resulting in a denial of service. (CVE-2022-3094) Borja Marcos discovered that Bind incorrectly handled certain RRSIG queries. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2022-3736) Maksym Odinintsev discovered that Bind incorrectly handled certain answers from stale cache. A remote attacker could possibly use this issue to cause Bind to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 22.10.
