Detailsinfo

A vulnerability, which was classified as critical, was found in Fabrice Bellard QEMU (Virtualization Software) (unknown version). Affected is an unknown code block of the component Header Field Handler. The manipulation of the argument catalog_size with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability.

The weakness was presented 03/26/2014 by Kevin Wolf with Red Hat as [Qemu-devel] [PATCH for-2.0 00/47] block: image format input validation as confirmed posting (Mailing List). The advisory is available at lists.gnu.org. This vulnerability is traded as CVE-2014-0143 since 12/03/2013. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 73656 (CentOS 6 : qemu-kvm (CESA-2014:0420)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 166916 (SUSE Enterprise Linux Security Update for kvm (SUSE-SU-2014:0623-1)).

Applying a patch is able to eliminate this problem. The bugfix is ready for download at lists.gnu.org. A possible mitigation has been published immediately after the disclosure of the vulnerability.
