USN-876-1: PostgreSQL vulnerabilities

3 January 2010

PostgreSQL vulnerabilities



It 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 machine-in-the-middle attack to view sensitive
information or alter encrypted communications. (CVE-2009-4034)

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)

Update instructions

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

Ubuntu 9.10
Ubuntu 9.04
Ubuntu 8.10
Ubuntu 8.04
Ubuntu 6.06

In general, a standard system upgrade is sufficient to effect the
necessary changes.
