OpenStack Security Advisory: 2012-009
CVE: CVE-2012-3371
Date: July 11, 2012
Title: Scheduler denial of service through scheduler_hints
Impact: Medium
Reporter: Dan Prince (Red Hat)
Products: Nova
Affects: Essex, Folsom series

Description:
Dan Prince from Red Hat reported a vulnerability in Nova scheduler
nodes. By creating servers with malicious scheduler_hints, an
authenticated user may generate a huge amount of database calls,
potentially resulting in a Denial of Service attack against Nova
scheduler nodes. Only setups exposing the OpenStack API and enabling
DifferentHostFilter and/or SameHostFilter are affected.
