Details

A flaw was discovered in the Linux kernel's KVM (kernel virtual machine).
An administrative user in the guest OS could leverage this flaw to cause a
denial of service in the host OS. (CVE-2012-2121)

Multiple integer overflow flaws were discovered in the Alchemy LCD frame-
buffer drivers in the Linux kernel. An unprivileged local user could
exploit this flaw to gain administrative privileges. (CVE-2013-4511)

Update instructions

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

Ubuntu 10.04

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.
