OrganizationPublishedContributorStatement
Red Hat2007-09-05Mark J CoxThe only effect of this bug is to cause the process to read from a random segment of memory, if a large "length" parameter is passed to the strspn/strcspn function, which is under the control of the script author. This bug has no security impact.
