Description Victor Pereira 2014-02-20 08:50:52 UTC 
CVE-2013-4531

cpreg_vmstate_indexes is a VARRAY_INT32. A negative value for
cpreg_vmstate_array_len will cause a buffer overflow.

An user able to alter the savevm data (either on the disk or over the wire
during migration) could use this flaw to to corrupt QEMU process memory on
the (destination) host, which could potentially result in arbitrary code
execution on the host with the privileges of the QEMU process.
