USN-5647-1: Linux kernel (GCP) vulnerabilities It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33655) Moshe Kol, Amit Klein and Yossi Gilad discovered that the IP implementation in the Linux kernel did not provide sufficient randomization when calculating port offsets. An attacker could possibly use this to expose sensitive information. (CVE-2022-1012, CVE-2022-32296) Norbert Slusarek discovered that a race condition existed in the perf subsystem in the Linux kernel, resulting in a use-after-free vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1729) It was discovered that the device-mapper verity (dm-verity) [ more… ]

USN-5646-1: libXi vulnerabilities Tobias Stoeckmann discovered that libXi did not properly manage memory when handling X server responses. A remote attacker could use this issue to cause libXi to crash, resulting in a denial of service. Source: USN-5646-1: libXi vulnerabilities

USN-5615-2: SQLite vulnerability USN-5615-1 fixed several vulnerabilities in SQLite. This update provides the corresponding fix for CVE-2020-35525 for Ubuntu 16.04 ESM. Original advisory details: It was discovered that SQLite incorrectly handled INTERSEC query processing. An attacker could use this issue to cause SQLite to crash, resulting in a denial of service, or possibly execute arbitrary code. Source: USN-5615-2: SQLite vulnerability
