Description Jan Lieskovsky 2010-10-01 15:11:42 UTC 
A flaw was found in the way PostgreSQL handled SQL functions, created
with SECURITY DEFINER keyword and implemented in PL/Perl or PL/Tcl
languages. Once the PL/Perl or PL/Tcl procedural language was registered
on particular database, a remote, authenticated user, running a
specially-crafted PL/Perl or PL/Tcl script could use this flaw to bypass
intended PostgreSQL SECURITY DEFINER function definition refinement /
protection mechanism, allowing them to run particular PostgreSQL function
under their effective user ID, potentially leading to escalation of their
privileges.
