Description Victor Pereira 2014-02-20 08:56:46 UTC 
CVE-2013-4541

s->setup_len and s->setup_index are fed into usb_packet_copy as
size/offset into s->data_buf, it's possible for invalid state to exploit
this to load arbitrary data.

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.
