USN-1996-1: Linux kernel vulnerability
22 October 2013
The system could be made to expose sensitive information to a local user.
Releases
Packages
- linux - Linux kernel
Details
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.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.10
-
linux-image-3.5.0-42-powerpc64-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-powerpc-smp
-
3.5.0-42.65
-
linux-image-3.5.0-42-generic
-
3.5.0-42.65
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.
