CentOS Errata and Security Advisory CESA-2008:0039
PostgreSQL is an advanced Object-Relational database management system (DBMS). The postgresql packages include the client programs and libraries needed to access a PostgreSQL DBMS server.
A privilege escalation flaw was discovered in PostgreSQL. An authenticated attacker could create an index function that would be executed with administrator privileges during database maintenance tasks, such as database vacuuming. (CVE-2007-6600)
A privilege escalation flaw was discovered in PostgreSQL's Database Link library (dblink). An authenticated attacker could use dblink to possibly escalate privileges on systems with "trust" or "ident" authentication configured. Please note that dblink functionality is not enabled by default, and can only by enabled by a database administrator on systems with the postgresql-contrib package installed. (CVE-2007-3278, CVE-2007-6601)
All postgresql users should upgrade to these updated packages, which include PostgreSQL 7.3.21 and resolve these issues.
