A vulnerability, which was classified as critical, was found in Red Hat Enterprise Virtualization 2.2 (Virtualization Software). Affected is some unknown functionality. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

QEMU-KVM, as used in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and KVM 83, does not properly validate guest QXL driver pointers, which allows guest OS users to cause a denial of service (invalid pointer dereference and guest OS crash) or possibly gain privileges via unspecified vectors.

The weakness was disclosed 08/24/2010 by Izik Eidus (Website). The advisory is available at rhn.redhat.com. This vulnerability is traded as CVE-2010-0431. Local access is required to approach this attack. A authentication is required for exploitation. The technical details are unknown and an exploit is not available.
