USN-5705-1: LibTIFF vulnerabilities Chintan Shah discovered that LibTIFF incorrectly handled memory in certain conditions. An attacker could trick a user into processing a specially crafted image file and potentially use this issue to allow for information disclosure or to cause the application to crash. (CVE-2022-3570) It was discovered that LibTIFF incorrectly handled memory in certain conditions. An attacker could trick a user into processing a specially crafted tiff file and potentially use this issue to cause a denial of service. (CVE-2022-3598) Source: USN-5705-1: LibTIFF vulnerabilities

USN-5706-1: Linux kernel (Azure CVM) vulnerabilities It was discovered that the BPF verifier in the Linux kernel did not properly handle internal data structures. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-4159) It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 (V4L2) implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-20369) Duoming Zhou discovered that race conditions existed in the timer handling implementation of the Linux kernel’s Rose X.25 protocol layer, resulting in use-after-free vulnerabilities. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-2318) Roger Pau Monné discovered that the Xen virtual block driver in the Linux kernel did not properly initialize memory pages to be used [ more… ]
