RHSA-2010:0908-01: [RHSA-2010:0908-01] postgresql: Moderate Advisory

Product: Red Hat Enterprise Linux

Summary: Updated postgresql packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

Description:

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.
