qemu-kvm - security update

A vulnerability was discovered in the qemu virtualisation solution:

• CVE-2015-3456
  Jason Geffner discovered a buffer overflow in the emulated floppy
  disk drive, resulting in the potential execution of arbitrary code.

Despite the end-of-life of qemu-kvm support in the old-oldstable
distribution (squeeze-lts), this problem has been fixed in version
0.12.5+dfsg-5+squeeze11 of the qemu-kvm source package due to its
severity (the so-called VENOM vulnerability).

Further problems may still be present in the qemu-kvm package in the
old-oldstable distribution (squeeze-lts) and users who need to rely on
qemu-kvm are encouraged to upgrade to a newer version of Debian.

We recommend that you upgrade your qemu-kvm packages.
