Detailsinfo

A vulnerability, which was classified as critical, was found in QEMU (Virtualization Software) (affected version not known). Affected is the function stellaris_enet_receive of the file hw/net/stellaris_enet.c of the component Stellaris ethernet Controller. 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:

Buffer overflow in the stellaris_enet_receive function in hw/net/stellaris_enet.c in QEMU, when the Stellaris ethernet controller is configured to accept large packets, allows remote attackers to cause a denial of service (QEMU crash) via a large packet.

The weakness was published 05/23/2016 with Intel (Website). The advisory is shared for download at lists.gnu.org. This vulnerability is traded as CVE-2016-4001 since 04/12/2016. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.
