Vendor Statements (disclaimer)

Official Statement from Red Hat (02/09/2007)

Red Hat does not consider this issue to be a security vulnerability. On Red Hat Enterprise Linux processes that change their effective UID do not dump core by default when they receive a fatal signal. Therefore the NULL pointer dereference does not lead to an information leak.
