From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020913 Description of problem: Quoted from the Postgresql site: "Due to recent security vulnerabilities reported on BugTraq, concerning several buffer overruns found in PostgreSQL, the PostgreSQL Global Development Team today released v7.2.2 of PostgreSQL that fixes these vulnerabilities. The following buffer overruns have been identified and addressed: * in handling long datetime input * in repeat() * in lpad() and rpad() with multibyte * in SET TIME ZONE and TZ env var " The version of PostgreSQL that was shipped with Red Hat Linux Advanced Server 2.1 was vulnerable to these buffer overruns. The multibyte code that can be exploited was not added until PostgreSQL 7.2, but it is part of my attached patch nonetheless.
