========================================================================== Ubuntu Security Notice USN-2871-1 January 19, 2016
linux vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
Summary:
The system could be made to crash or run programs as an administrator.
Software Description: - linux: Linux kernel
Details:
Yevgeny Pats discovered that the session keyring implementation in the Linux kernel did not properly reference count when joining an existing session keyring. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.04: linux-image-3.19.0-47-generic 3.19.0-47.53 linux-image-3.19.0-47-generic-lpae 3.19.0-47.53 linux-image-3.19.0-47-lowlatency 3.19.0-47.53 linux-image-3.19.0-47-powerpc-e500mc 3.19.0-47.53 linux-image-3.19.0-47-powerpc-smp 3.19.0-47.53 linux-image-3.19.0-47-powerpc64-emb 3.19.0-47.53 linux-image-3.19.0-47-powerpc64-smp 3.19.0-47.53
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.
