Details
Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An
unprivileged local user could exploit this flaw to cause a denial of
service (system crash) or gain administrative privileges. (CVE-2014-3153)
A flaw was discovered in the vhost-net subsystem of the Linux kernel. Guest
OS users could exploit this flaw to cause a denial of service (host OS
crash). (CVE-2014-0055)
Sasha Levin reported a bug in the Linux kernel's virtual memory management
subsystem. An unprivileged local user could exploit this flaw to cause a
denial of service (system crash). (CVE-2014-3122)
Update instructions
The problem can be corrected by updating your system to the following package versions:

-
linux-image-3.2.0-64-powerpc64-smp
-
3.2.0-64.97
-
linux-image-3.2.0-64-highbank
-
3.2.0-64.97
-

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.
