Description

An information leak was discovered in Nova. An attacker with access to a valid EC2_ACCESS_KEY could obtain the corresponding EC2_SECRET_KEY for that user.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
