========================================================================== Ubuntu Security Notice USN-2975-2 May 16, 2016
linux-lts-trusty 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-lts-trusty: Linux hardware enablement kernel from Trusty for Precise
Details:
USN-2975-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 LTS.
Philip Pettersson discovered that the Linux kernel's ASN.1 DER decoder did not properly process certificate files with tags of indefinite length. A local unprivileged 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 12.04 LTS: linux-image-3.13.0-86-generic 3.13.0-86.131~precise1 linux-image-3.13.0-86-generic-lpae 3.13.0-86.131~precise1
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-trusty, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
