Red Hat Security Advisory 2013-0856-01 - Red Hat Certificate System is an enterprise software system designed to manage enterprise Public Key Infrastructure deployments. The Token Processing System is a PKI subsystem that acts as a Registration Authority for authenticating and processing enrollment requests, PIN reset requests, and formatting requests from the Enterprise Security Client. A format string flaw was found in the TPS subsystem. An authenticated Certificate System user could use this flaw to crash the Apache HTTP Server child process, possibly interrupting the processing of other users' requests, or possibly execute arbitrary code with pkiuser privileges.
