Summary

Jason Geffner discovered a buffer overflow in the emulated floppy
disk drive, resulting in the potential execution of arbitrary code.
This only affects HVM guests.

For the oldstable distribution (wheezy), this problem has been fixed
in version 4.1.4-3+deb7u6.

The stable distribution (jessie) is already fixed through the qemu
update provided as DSA-3259-1.

We recommend that you upgrade your xen packages.
