NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

The qcow2_open function in the (block/qcow2.c) in QEMU before 1.7.2 and 2.x before 2.0.0 allows local users to cause a denial of service (NULL pointer dereference) via a crafted image which causes an error, related to the initialization of the snapshot_offset and nb_snapshots fields.
