DESCRIPTION:
A weakness has been reported in OpenStack Compute (Nova), which can
be exploited by malicious people to disclose sensitive information.

The weakness is caused due to an error when handling error messages
during an authentication request. This can be exploited to disclose
the EC2_SECRET_KEY by sending invalid login requests.

Successful exploitation requires knowing or guessing the
EC2_ACCESS_KEY, which is considered confidential and is not normally
shared.

The weakness is reported in version 2011.3 (Diablo).

SOLUTION:
Fixed in the GIT repository.

PROVIDED AND/OR DISCOVERED BY:
Reported by Stanislaw Pitucha in a bug report.
