Ubuntu 14.04 ESM USN-5916-1 Critical: Denial Of Service Kernel Risk

The system could be made to crash or run programs as an administrator.. =========================================================================Ubuntu Security Notice USN-5916-1 March 03, 2023 linux vulnerability ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 ESM Summary: The system could be made to crash or run programs as an administrator. Software Description: - linux: Linux kernel Details: Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: linux-image-3.13.0-192-generic 3.13.0-192.243 linux-image-3.13.0-192-lowlatency 3.13.0-192.243 linux-image-generic 3.13.0.192.202 linux-image-generic-lts-trusty 3.13.0.192.202 linux-image-lowlatency 3.13.0.192.202 linux-image-server 3.13.0.192.202 linux-image-virtual 3.13.0.192.202 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
