OrganizationPublishedContributorStatement
Red Hat2007-02-09Mark J CoxRed 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.
