Multiple cross-site scripting (XSS) flaws were found in the way:

1) 'displayCRL' script of Certificate System sanitized content of 'pageStart' and 'pageSize' variables provided in the query string,

2) 'profileProcess' script of Certificate System sanitized content of 'nonce' variable provided in the query string.

A remote attacker could provide a specially-crafted web page that, when visited by an unsuspecting Certificate System user would lead to arbitrary HTML or web script execution in the context of Certificate System user session.

A denial of service flaw was found in the way token processing system of Certificate System processed interrupted token format operations. A local attacker, via suddenly interrupting the token format operation, could use this flaw to cause pki-tps infrastructure to crash with NULL pointer dereference, subsequently leading to relevant Apache httpd web server worker it to need to restart, rendering it to be unavailable for short period of time possibly halting (already) in-progress operations of other users.
