Description

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

Two bugs that can lead to buffer overflows have been found in the PostgreSQL abstract data type to ASCII conversion routines. A remote attacker who is able to influence the data passed to the to_ascii functions may be able to execute arbitrary code in the context of the PostgreSQL server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0901 to these issues.

In addition, a bug that can lead to leaks has been found in the string to timestamp abstract data type conversion routine. If the input string to the to_timestamp() routine is shorter than what the template string is expecting, the routine will run off the end of the input string, resulting in a leak and unstable behaviour.

Users of PostgreSQL are advised to upgrade to these erratum packages, which contain a backported patch that corrects these issues.
