An authenticated PostgreSQL user has the ability to crash the database server or possibly read arbitrary memory for the server process. This is caused by insufficient type checking for SQL-language functions.

Note that in RHEL3, the relevant package is rh-postgresql ... we don't ship a plain "postgresql" package in that branch, for long-obsolete reasons.
