- Ubuntu 12.04 LTS
- Ubuntu 11.10

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)

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
