USN-3908-1: Linux kernel vulnerability

linux vulnerability

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-generic3.13.0-166.216
linux-image-3.13.0-166-generic-lpae3.13.0-166.216
linux-image-3.13.0-166-lowlatency3.13.0-166.216
linux-image-3.13.0-166-powerpc-e5003.13.0-166.216
linux-image-3.13.0-166-powerpc-e500mc3.13.0-166.216
linux-image-3.13.0-166-powerpc-smp3.13.0-166.216

linux-image-3.13.0-166-powerpc64-smp3.13.0-166.216
linux-image-generic3.13.0.166.177
linux-image-generic-lpae3.13.0.166.177
linux-image-lowlatency3.13.0.166.177
linux-image-powerpc-e5003.13.0.166.177
linux-image-powerpc-e500mc3.13.0.166.177
linux-image-powerpc-smp3.13.0.166.177
linux-image-powerpc64-emb3.13.0.166.177
linux-image-powerpc64-smp3.13.0.166.177
linux-image-virtual3.13.0.166.177

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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.
