7.2 - USN-3144-1

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

- Ubuntu 12.04 LTS

Summary:

The system could be made to crash under certain conditions.

Software Description: - linux: Linux kernel

Details:

Marco Grassi discovered that the driver for Areca RAID Controllers in the Linux kernel did not properly validate control messages. A local attacker could use this to cause a denial of service (system crash) or possibly gain privileges.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-116-generic 3.2.0-116.158
linux-image-3.2.0-116-generic-pae 3.2.0-116.158
linux-image-3.2.0-116-highbank 3.2.0-116.158
linux-image-3.2.0-116-omap 3.2.0-116.158
linux-image-3.2.0-116-powerpc-smp 3.2.0-116.158
linux-image-3.2.0-116-powerpc64-smp 3.2.0-116.158
linux-image-3.2.0-116-virtual 3.2.0-116.158
linux-image-generic 3.2.0.116.132
linux-image-generic-pae 3.2.0.116.132
linux-image-highbank 3.2.0.116.132
linux-image-omap 3.2.0.116.132
linux-image-powerpc-smp 3.2.0.116.132
linux-image-powerpc64-smp 3.2.0.116.132
linux-image-virtual 3.2.0.116.132

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.
