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.");
