CVE-2011-0011

Setting the VNC password to an empty string silently disabled all authentication.

CVE-2011-1750

The virtio-blk driver performed insufficient validation of read/write I/O from the guest instance, which could lead to denial of service or privilege escalation.

The oldstable distribution (lenny) is not affected by this problem.

For the stable distribution (squeeze), this problem has been fixed in version 0.12.5+dfsg-5+squeeze1.

The unstable distribution (sid) will be fixed soon.

We recommend that you upgrade your qemu-kvm packages.");
