Description Josh Bressers 2007-04-24 18:46:32 UTC
+++ This bug was initially created as a clone of Bug #237680 +++

Quoting the PostgreSQL release notes:

    Support explicit placement of the temporary-table schema within search_path, 
    and disable searching it for functions and operators (Tom)

    This is needed to allow a security-definer function to set a truly secure 
    value of search_path. Without it, an unprivileged SQL user can use temporary 
    objects to execute code with the privileges of the security-definer function 
    (CVE-2007-2138). See CREATE FUNCTION for more information.

This flaw also affects FC5 and FC7
