The remote Scientific Linux host is missing one or more security
It was discovered that a user could utilize the features of the
PL/Perl and PL/Tcl languages to modify the behavior of a SECURITY
DEFINER function created by a different user. If the PL/Perl or PL/Tcl
language was used to implement a SECURITY DEFINER function, an
authenticated database user could use a PL/Perl or PL/Tcl script to
modify the behavior of that function during subsequent calls in the
same session. This would result in the modified or injected code also
being executed with the privileges of the user who created the
SECURITY DEFINER function, possibly leading to privilege escalation.
