Detail

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

- Ubuntu 12.04 LTS

Summary:

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

Software Description: - linux-ti-omap4: Linux kernel for OMAP4

Details:

Chiachih Wu, Yuan-Tsung Lo, and Xuxian Jiang discovered that the legacy ABI for ARM (OABI) had incomplete access checks for epoll_wait(2) and semtimedop(2). A local attacker could use this to possibly execute arbitrary code.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-1488-omap4 3.2.0-1488.115

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.
