Description Prasad Pandit 2014-03-19 12:45:43 UTC
Qemu block driver for the QCOW version 2 format is vulnerable to a NULL pointer
dereference flaw. It could occur in case of an error in reading a qcow2 image
file, after the 'snapshot_offset' & 'nb_snapshots' fields have been
initialised.

An user able to alter the Qemu disk image could use this flaw to crash the Qemu
instance resulting in Dos.
