Official Statement fromRed Hat (11/04/2009)

The Red Hat Security Response Team has rated this issue as having moderate security impact. We currently have no plans to fix this flaw in Red Hat Enterprise Linux 3, 4, and 5 as it is not possible to trigger the information leak if the suid_dumpable tunable is set to zero (which is the default). It was addressed in Red Hat Enterprise MRG via: https://rhn.redhat.com/errata/RHSA-2009-1540.html
