New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that PostgreSQL incorrectly handled certain bytes passed to the crypt() function when using DES encryption. An attacker could use this flaw to incorrectly handle authentication.
It was discovered that PostgreSQL incorrectly handled SECURITY DEFINER and SET attributes on procedural call handlers. An attacker could use this flaw to cause PostgreSQL to crash, leading to a denial of service. (CVE-2012-2655).
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.
SolutionUpdate the affected postgresql-8.3, postgresql-8.4 and / or postgresql-9.1 packages.
