Name of the Vulnerable Software and Affected Versions: QEMU (affected versions not specified) Description: A flaw was found in QEMU, in the virtio-scsi, virtio-blk, and virtio-crypto devices. The size for `virtqueue push` as set in `virtio scsi complete req`, `virtio blk req complete`, and `virtio crypto req complete` could be larger than the true size of the data sent to the guest. This may lead to an information leak due to uninitialized data in the `bounce.buffer`. Attackers may crash the system or execute code. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

The issue is related to insufficient input validation in the Core component of Oracle VM VirtualBox, allowing a high-privileged attacker with logon to the infrastructure to compromise Oracle VM VirtualBox. Successful attacks can result in unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data and the ability to cause a hang or frequently repeatable crash of Oracle VM VirtualBox. This may significantly impact additional products due to scope change.
