Description Jan Lieskovsky 2012-08-17 15:03:21 UTC 
An XML External Entities (XXE) attack was found in the way xmlparse routine, used for producing of xml data type value from character data, of PostgreSQL, an advanced Object-Relational database management system (DBMS), performed parsing of provided character data. An unprivileged database user could issue a specially-crafted SQL query to the PostgreSQL server that, when processed could lead to attacker's ability to read arbitrary system files, accessible with privileges of the user running the PostgreSQL server.
