Description Jan Lieskovsky 2013-02-05 08:33:34 EST
An array index error, leading to out of heap-based buffer bounds read flaw was found in the way PostgreSQL, an advanced Object-Relational database management system (DBMS), performed retrieval of textual form of error message representation when processing certain enumeration types. An unprivileged database user could issue a specially-crafted SQL query that, when processed by the server component of the PostgreSQL service, would lead to denial of service (daemon crash) or disclosure (of certain portions of) server memory.
