Ubuntu Security Notice USN-6319-1

Ubuntu Security Notice 6319-1 - Daniël Trujillo, Johannes Wikner, and Kaveh Razavi discovered that some AMD processors utilising speculative execution and branch prediction may allow unauthorized memory reads via a speculative side-channel attack. A local attacker could use this to expose sensitive information, including kernel memory.

Ubuntu Security Notice USN-6317-1

Ubuntu Security Notice 6317-1 - Daniel Moghimi discovered that some Intel Processors did not properly clear microarchitectural state after speculative execution of various instructions. A local unprivileged user could use this to obtain to sensitive information. Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain vector register instructions. A local attacker could use this to expose sensitive information.

Ubuntu Security Notice USN-6314-1

Ubuntu Security Notice 6314-1 - It was discovered that the netlink implementation in the Linux kernel did not properly validate policies when parsing attributes in some situations. An attacker could use this to cause a denial of service. Billy Jheng Bing Jhong discovered that the CIFS network file system implementation in the Linux kernel did not properly validate arguments to ioctl in some situations. A local attacker could possibly use this to cause a denial of service.

CVE-2023-39615: Global-buffer-overflow at /libxml2/SAX2.c:1614 in xmlSAX2StartElement() (SIGSEGV) (#535) · Issues · GNOME / libxml2 · GitLab

Xmlsoft Libxml2 v2.11.0 was discovered to contain a global buffer overflow via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted XML file.

Ubuntu Security Notice USN-6313-1

Ubuntu Security Notice 6313-1 - It was discovered that FAAD2 incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to execute arbitrary code.
