Description Jan Lieskovsky 2012-11-14 15:20:35 UTC
A denial of service flaw was found in the way the TraceManager of Firebird, a SQL relational database management system, performed preparation of an empty dynamic SQL query. When the trace mode was enabled, a remote, authenticated database user could use this flaw to cause the Firebird server to crash with a NULL pointer dereference.
