Debian DSA-2120-1 : postgresql-8.3 - privilege escalation

medium Nessus Plugin ID 49966

Language:

Synopsis

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

Description

Tim Bunce discovered that PostgreSQL, a database server software, does not properly separate interpreters for server-side stored procedures which run in different security contexts. As a result, non-privileged authenticated database users might gain additional privileges.

Note that this security update may impact intended communication through global variables between stored procedures. It might be necessary to convert these functions to run under the plperlu or pltclu languages, with database superuser privileges.

This security update also includes unrelated bug fixes from PostgreSQL 8.3.12.

Solution

Upgrade the PostgreSQL packages.

For the stable distribution (lenny), this problem has been fixed in version 8.3_8.3.12-0lenny1.
