It 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.
(CVE-2012-2143)

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.
