USN-5630-1: Linux kernel (Raspberry Pi) 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 [ more… ]

USN-5628-1: etcd vulnerabilities It was discovered that etcd incorrectly handled certain specially crafted WAL files. An attacker could possibly use this issue to cause a denial of service. (CVE-2020-15106, CVE-2020-15112) It was discovered that etcd incorrectly handled directory permissions when trying to create a directory that exists already. An attacker could possibly use this issue to obtain sensitive information. (CVE-2020-15113) It was discovered that etcd incorrectly handled endpoint setup. An attacker could possibly use this issue to cause a denial of service. (CVE-2020-15114) Source: USN-5628-1: etcd vulnerabilities

USN-5627-1: PCRE vulnerabilities It was discovered that PCRE incorrectly handled memory when handling certain regular expressions. An attacker could possibly use this issue to cause applications using PCRE to expose sensitive information. Source: USN-5627-1: PCRE vulnerabilities
