========================================================================== Ubuntu Security Notice USN-3248-1 March 29, 2017
linux, 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 or run programs as an administrator.
Software Description: - linux: Linux kernel - linux-ti-omap4: Linux kernel for OMAP4
Details:
It was discovered that the xfrm framework for transforming packets in the Linux kernel did not properly validate data received from user space. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code with administrative privileges.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.2.0-125-generic 3.2.0-125.168 linux-image-3.2.0-125-generic-pae 3.2.0-125.168 linux-image-3.2.0-125-highbank 3.2.0-125.168 linux-image-3.2.0-125-omap 3.2.0-125.168 linux-image-3.2.0-125-powerpc-smp 3.2.0-125.168 linux-image-3.2.0-125-powerpc64-smp 3.2.0-125.168 linux-image-3.2.0-125-virtual 3.2.0-125.168 linux-image-3.2.0-1503-omap4 3.2.0-1503.130 linux-image-generic 3.2.0.125.140 linux-image-generic-pae 3.2.0.125.140 linux-image-highbank 3.2.0.125.140 linux-image-omap 3.2.0.125.140 linux-image-omap4 3.2.0.1503.98 linux-image-powerpc-smp 3.2.0.125.140 linux-image-powerpc64-smp 3.2.0.125.140 linux-image-virtual 3.2.0.125.140
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.
