Description Petr Matousek 2014-02-18 10:22:18 UTC
s->arglen is taken from wire and used as idx in ssi_sd_transfer().

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.

Upstream fix:
