SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that PostgreSQL did not properly handle certificates with NULL characters in the Common Name field of X.509 certificates.
An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications.
It was discovered that PostgreSQL did not properly manage session-local state. A remote authenticated user could exploit this to escalate priviliges within PostgreSQL. (CVE-2009-4136).
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.
