Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS

Summary:

The system could be made to run programs as an administrator.

Software Description: - linux: Linux kernel

Details:

Jann Horn discovered a race condition in the fork() system call in the Linux kernel. A local attacker could use this to gain access to services that cache authorizations.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 LTS:
linux-image-3.13.0-166-generic 3.13.0-166.216
linux-image-3.13.0-166-generic-lpae 3.13.0-166.216
linux-image-3.13.0-166-lowlatency 3.13.0-166.216
linux-image-3.13.0-166-powerpc-e500 3.13.0-166.216
linux-image-3.13.0-166-powerpc-e500mc 3.13.0-166.216
linux-image-3.13.0-166-powerpc-smp 3.13.0-166.216
linux-image-3.13.0-166-powerpc64-emb 3.13.0-166.216
linux-image-3.13.0-166-powerpc64-smp 3.13.0-166.216
linux-image-generic 3.13.0.166.177
linux-image-generic-lpae 3.13.0.166.177
linux-image-lowlatency 3.13.0.166.177
linux-image-powerpc-e500 3.13.0.166.177
linux-image-powerpc-e500mc 3.13.0.166.177
linux-image-powerpc-smp 3.13.0.166.177
linux-image-powerpc64-emb 3.13.0.166.177
linux-image-powerpc64-smp 3.13.0.166.177
linux-image-virtual 3.13.0.166.177

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.
