Ubuntu Security Notice USN-3150-2
December 06, 2016
linux-ti-omap4 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-ti-omap4: Linux kernel for OMAP4
Details:
Philip Pettersson discovered a race condition in the af_packet
implementation in the Linux kernel. A local unprivileged attacker could use
this to cause a denial of service (system crash) or run 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-3.2.0-1496-omap4 3.2.0-1496.123
linux-image-omap4 3.2.0.1496.91
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.
