Several vulnerabilities were discovered in the qemu virtualisation
solution:

    It was discovered that the IDE controller emulation is susceptible
    to denial of service.

CVE-2015-3456

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

For the oldstable distribution (wheezy), these problems have been fixed
in version 1.1.2+dfsg-6a+deb7u7 of the qemu source package and in version
1.1.2+dfsg-6+deb7u7 of the qemu-kvm source package. Only CVE-2015-3456
affects oldstable.

For the stable distribution (jessie), these problems have been fixed in
version 1:2.1+dfsg-12.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your qemu packages.
