Mandriva Linux Security Advisory : postgresql (MDVSA-2008:004)

Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Index Functions Privilege Escalation (CVE-2007-6600): as a unique
feature, PostgreSQL allows users to create indexes on the results of
user-defined functions, known as expression indexes. This provided two
vulnerabilities to privilege escalation: (1) index functions were
executed as the superuser and not the table owner during VACUUM and
ANALYZE, and (2) that SET ROLE and SET SESSION AUTHORIZATION were
permitted within index functions.

Regular Expression Denial-of-Service (CVE-2007-4772, CVE-2007-6067,
CVE-2007-4769): three separate issues in the regular expression
libraries used by PostgreSQL allowed malicious users to initiate a
denial-of-service by passing certain regular expressions in SQL
queries. First, users could create infinite loops using some specific
regular expressions. Second, certain complex regular expressions could
consume excessive amounts of memory. Third, out-of-range backref
numbers could be used to crash the backend.

DBLink Privilege Escalation (CVE-2007-6601): DBLink functions combined
with local trust or ident authentication could be used by a malicious
user to gain superuser privileges. This issue has been fixed, and does
not affect users who have not installed DBLink (an optional module),
or who are using password authentication for local access. This same
problem was addressed in the previous release cycle (see
CVE-2007-3278), but that patch failed to close all forms of the
loophole.

Updated packages fix these issues by upgrading to the latest
maintenance versions of PostgreSQL.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.2
