Vulnerability Assessment Details

RHSA-2006-0526: rh-postgres

Vulnerability Assessment Summary
Check for the version of the rh packages

Detailed Explanation for this Vulnerability Assessment

Updated postgresql packages that fix several security vulnerabilities are
now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

PostgreSQL is an advanced Object-Relational database management system
(DBMS).

A bug was found in the way PostgreSQL's PQescapeString function escapes
strings when operating in a multibyte character encoding. It is possible
for a possible hacker to provide an application a carefully crafted string
containing invalidly-encoded characters, which may be improperly escaped,
permiting the attacker to inject malicious SQL. While this update fixes how
PQescapeString operates, the PostgreSQL server has also been modified to
prevent such an attack occurring through unpatched clients.
(CVE-2006-2313, CVE-2006-2314). More details about this issue are
available in the linked PostgreSQL technical documentation.

An integer signedness bug was found in the way PostgreSQL generated
password salts. The actual salt size is only half the size of the expected
salt, making the process of brute forcing password hashes slightly easier.
This update will not strengthen already existing passwords, but all newly
assigned passwords will have the proper salt length. (CVE-2006-0591)

Users of PostgreSQL should upgrade to these updated packages containing
PostgreSQL version 7.4.13, which corrects these issues.
