Debian DSA-2282-1 Moderate: KVM Privilege Escalation Threats

Two vulnerabilities have been discovered in KVM, a solution for full
virtualization on x86 hardware:

CVE-2011-2212

Nelson Elhage discovered a buffer overflow in the virtio subsystem,
which could lead to denial of service or privilege escalation.

CVE-2011-2527

Andrew Griffiths discovered that group privileges were
insufficiently dropped when started with -runas option, resulting
in privilege escalation.

For the stable distribution (squeeze), this problem has been fixed in
version 0.12.5+dfsg-5+squeeze6.

For the unstable distribution (sid), this problem has been fixed in
version 0.14.1+dfsg-3.

We recommend that you upgrade your qemu-kvm packages.
