========================================================================== Ubuntu Security Notice USN-2596-1 May 05, 2015
linux vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
The system could be made to run programs as an administrator.
Software Description: - linux: Linux kernel
Details:
A race condition between chown() and execve() was discovered in the Linux kernel. A local attacker could exploit this race by using chown on a setuid-user-binary to gain administrative privileges.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: linux-image-3.2.0-83-generic 3.2.0-83.120 linux-image-3.2.0-83-generic-pae 3.2.0-83.120 linux-image-3.2.0-83-highbank 3.2.0-83.120 linux-image-3.2.0-83-omap 3.2.0-83.120 linux-image-3.2.0-83-powerpc-smp 3.2.0-83.120 linux-image-3.2.0-83-powerpc64-smp 3.2.0-83.120 linux-image-3.2.0-83-virtual 3.2.0-83.120
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.
