========================================================================== Ubuntu Security Notice USN-2840-2 December 17, 2015 linux-ti-omap4 vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS Summary: The system could be made to crash under certain conditions. Software Description: - linux-ti-omap4: Linux kernel for OMAP4 Details: Dmitry Vyukov discovered that the Linux kernel's keyring handler attempted to garbage collect incompletely instantiated keys. A local unprivileged attacker could use this to cause a denial of service (system crash). Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: linux-image-3.2.0-1475-omap4 3.2.0-1475.97 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. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
