SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionIt was discovered that a user could utilize the features of the PL/Perl andaPL/Tcl languages to modify the behavior of a SECURITY DEFINER functionacreated by a different user. If the PL/Perl or PL/Tcl language was used toaimplement a SECURITY DEFINER function, an authenticated database user couldause a PL/Perl or PL/Tcl script to modify the behavior of that functionaduring subsequent calls in the same session. This would result in theamodified or injected code also being executed with the privileges of theauser who created the SECURITY DEFINER function, possibly leading to privilege escalation.
