USN-5733-1: FLAC vulnerabilities It was discovered that FLAC was not properly performing memory management operations, which could result in a memory leak. An attacker could possibly use this issue to cause FLAC to consume resources, leading to a denial of service. (CVE-2017-6888) It was discovered that FLAC was not properly performing bounds checking operations when encoding or decoding data. If a user or automated system were tricked into processing a specially crafted file, an attacker could possibly use this issue to expose sensitive information or to cause FLAC to crash, leading to a denial of service.

USN-5729-2: Linux kernel vulnerabilities It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-20422) Hsin-Wei Hung discovered that the BPF subsystem in the Linux kernel contained an out-of-bounds read vulnerability in the x86 JIT compiler. A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2022-2905) Hao Sun and Jiacheng Xu discovered that the NILFS file system implementation in the Linux kernel contained 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-2022-2978) Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in the Linux kernel. A local attacker could [ more… ]
