USN-5932-1: Sofia-SIP vulnerabilities It was discovered that Sofia-SIP incorrectly handled specially crafted SDP packets. A remote attacker could use this issue to cause applications using Sofia-SIP to crash, leading to a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. (CVE-2022-31001, CVE-2022-31002, CVE-2022-31003) It was discovered that Sofia-SIP incorrectly handled specially crafted UDP packets. A remote attacker could use this issue to cause applications using Sofia-SIP to crash, leading to a denial of service. (CVE-2022-47516) Qiuhao Li discovered that Sofia-SIP incorrectly handled specially crafted STUN packets. A remote attacker could use this issue to cause applications using Sofia-SIP to crash, leading to a denial of service, or possibly execute arbitrary code.

LSN-0092-1: Kernel Live Patch Security Notice Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code.(CVE-2022-4378) 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 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) Source: LSN-0092-1: Kernel Live Patch Security Notice

USN-5929-1: Linux kernel (Raspberry Pi) vulnerabilities It was discovered that the Upper Level Protocol (ULP) subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, 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-2023-0461) Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-0179) It was discovered that the NVMe driver in the Linux kernel did not properly handle reset events in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3169) Maxim Levitsky discovered that the KVM nested virtualization [ more… ]
