Debian: DSA-2933-1 Critical: Qemu-Kvm Buffer Overflow Threat

Several vulnerabilities were discovered in qemu-kvm, a full
virtualization solution on x86 hardware.

CVE-2013-4344

Buffer overflow in the SCSI implementation in QEMU,
when a SCSI controller has more than 256 attached devices, allows
local users to gain privileges via a small transfer buffer in a
REPORT LUNS command.

CVE-2014-2894

Off-by-one error in the cmd_smart function in the smart self test in
hw/ide/core.c in QEMU allows local users to have
unspecified impact via a SMART EXECUTE OFFLINE command that triggers a buffer underflow and memory corruption.

For the stable distribution (wheezy), these problems have been fixed in
version 1.1.2+dfsg-6+deb7u3.

We recommend that you upgrade your qemu-kvm packages.
