postgresql-7.4 postgresql-8.1 postgresql-8.3 - several vulnerabilities

Several vulnerabilities have been discovered in PostgreSQL, a database
server. The Common Vulnerabilities and Exposures project identifies
the following problems:

It was discovered that PostgreSQL did not properly verify the Common
Name attribute in X.509 certificates, enabling attackers to bypass the
(optional) TLS protection on client-server connections, by relying on
a certificate from a trusted CA which contains an embedded NUL byte in
the Common Name (CVE-2009-4034).

Authenticated database users could elevate their privileges by
creating specially-crafted index functions (CVE-2009-4136).

The following matrix shows fixed source package versions for the
respective distributions.

In addition to these security fixes, the updates contain reliability
improvements and fix other defects.

We recommend that you upgrade your PostgreSQL packages.
