    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.
