Ubuntu Security Notice USN-1677-1
December 20, 2012

linux vulnerability
==========================================================================

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

- Ubuntu 11.10

Summary:

The system could be made to crash under certain conditions.

Software Description:
- linux: Linux kernel

Details:

A flaw was discovered in the Linux kernel's handling of new hot-plugged
memory. An unprivileged local user could exploit this flaw to cause a
denial of service by crashing the system.

Update instructions:

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

Ubuntu 11.10:
linux-image-3.0.0-29-generic 3.0.0-29.46
linux-image-3.0.0-29-generic-pae 3.0.0-29.46
linux-image-3.0.0-29-omap 3.0.0-29.46
linux-image-3.0.0-29-powerpc 3.0.0-29.46
linux-image-3.0.0-29-powerpc-smp 3.0.0-29.46
linux-image-3.0.0-29-powerpc64-smp 3.0.0-29.46
linux-image-3.0.0-29-server 3.0.0-29.46
linux-image-3.0.0-29-virtual 3.0.0-29.46

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.
