Ubuntu Security Notice USN-1669-1
December 18, 2012

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

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:

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 12.04 LTS:
linux-image-3.2.0-35-generic 3.2.0-35.55
linux-image-3.2.0-35-generic-pae 3.2.0-35.55
linux-image-3.2.0-35-highbank 3.2.0-35.55
linux-image-3.2.0-35-omap 3.2.0-35.55
linux-image-3.2.0-35-powerpc-smp 3.2.0-35.55
linux-image-3.2.0-35-powerpc64-smp 3.2.0-35.55
linux-image-3.2.0-35-virtual 3.2.0-35.55

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.

==========================================================================

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-ti-omap4: Linux kernel for OMAP4

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

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-1423-omap4 3.2.0-1423.30

After a standard system update you need to reboot your computer to make
all the necessary changes.
