Ubuntu Security Notice 5929-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5928-1 - It was discovered that systemd did not properly validate the time and accuracy values provided to the format_timespan function. An attacker could possibly use this issue to cause a buffer overrun, leading to a denial of service attack. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. It was discovered that systemd did not properly manage the fs.suid_dumpable kernel configurations. A local attacker could possibly use this issue to expose sensitive information. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 22.10.

Ubuntu Security Notice 5927-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 5926-1 - Kirill Tkhai discovered that the XFS file system implementation in the Linux kernel did not calculate size correctly when pre-allocating space in some situations. A local attacker could use this to expose sensitive information. Lee Jones discovered that a use-after-free vulnerability existed in the Bluetooth implementation in the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5925-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the Kernel Connection Multiplexor socket implementation in the Linux kernel when releasing sockets in certain situations. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 5924-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the System V IPC implementation in the Linux kernel did not properly handle large shared memory counts. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 5923-1 - It was discovered that LibTIFF could be made to read out of bounds when processing certain malformed image files with the tiffcrop tool. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause tiffcrop to crash, resulting in a denial of service. It was discovered that LibTIFF could be made to write out of bounds when processing certain malformed image files with the tiffcrop tool. If a user were tricked into opening a specially crafted image file, an attacker could possibly use this issue to cause tiffcrop to crash, resulting in a denial of service, or possibly execute arbitrary code.
