CVE-2012-4556: Input Validation
First published: Wed Oct 24 2012(Updated: )
A temporary denial of service flaw was found in the way token processing system of Certificate System processed user certificate search queries with certain empty search fields. A remote attacker could use this flaw to cause the main Apache httpd web server broker it to need to restart (resulting into situation where the client would obtain connection reset instead of proper error message), leading to (temporary) denial of service (resulting into any users currently in the middle of enrolling tokens to experience a connection drop and their in progress operation to be terminated).
