Package : qemu-kvm Vulnerability : several Problem type : remote Debian-specific: no CVE ID : CVE-2011-0011 CVE-2011-1750 Debian Bug : 611134 624177

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

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.
