USN-2928-2: Linux kernel (OMAP4) vulnerability
Ubuntu Security Notice USN-2928-2
14th March, 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
by someone with physical access.
Software description
- linux-ti-omap4
– Linux kernel for OMAP4
Details
Andrey Konovalov discovered that the ALSA USB MIDI driver incorrectly
performed a double-free. A local attacker with physical access 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 version:
- Ubuntu 12.04 LTS:
-
linux-image-3.2.0-1479-omap4
3.2.0-1479.105
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.
