Ubuntu Security Notice USN-1996-1
21st October, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
The system could be made to expose sensitive information to a local user.
- linux - Linux kernel
Dan Carpenter discovered an information leak in the HP Smart Array and
Compaq SMART2 disk-array driver in the Linux kernel. A local user could
exploit this flaw to obtain sensitive information from kernel memory.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 12.10:
- linux-image-3.5.0-42-powerpc-smp 3.5.0-42.65
- linux-image-3.5.0-42-highbank 3.5.0-42.65
- linux-image-3.5.0-42-omap 3.5.0-42.65
- linux-image-3.5.0-42-powerpc64-smp 3.5.0-42.65
- linux-image-3.5.0-42-generic 3.5.0-42.65
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. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
