Description

PostgreSQL's contains several vulnerabilities:

• John Heasman discovered that the LOAD extension is vulnerable to local privilege escalation (CAN-2005-0227).
• It is possible to bypass the EXECUTE permission check for functions (CAN-2005-0244).
• The PL/PgSQL parser is vulnerable to heap-based buffer overflow (CAN-2005-0244).
• The intagg contrib module is vulnerable to a Denial of Service (CAN-2005-0246).
