DESCRIPTION:
A vulnerability has been reported in OpenStack Compute (Nova), which
can be exploited by malicious users to cause a DoS (Denial of
Service).

The vulnerability is caused due to an error in the Nova scheduler
node when handling requests with "scheduler_hints" parameter and can
be exploited to cause the nodes to hang via multiple specially
crafted requests.

Successful exploitation requires the "DifferentHostFilter" or
"SameHostFilter" options to be enabled (disabled by default).

SOLUTION:
Fixed in the GIT repository.

PROVIDED AND/OR DISCOVERED BY:
The vendor credits Dan Prince, Red Hat.
