Debian DSA-1964-1 : postgresql-7.4, postgresql-8.1, postgresql-8.3 - several vulnerabilities

medium Nessus Plugin ID 44829

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

 oldstable/etch stable/lenny testing/unstable postgresql-7.4 7.4.27-0etch1 postgresql-8.1 8.1.19-0etch1 postgresql-8.3 8.3.9-0lenny1 8.3.9-1 postgresql-8.4 8.4.2-1 In addition to these security fixes, the updates contain reliability improvements and fix other defects.

Solution

Upgrade the PostgreSQL packages.
