Red Hat Certificate System (RHCS) is an enterprise software system designed to manage enterprise Public Key Infrastructure (PKI) deployments. Multiple cross-site scripting flaws were discovered in the Red Hat Certificate System. An attacker could use these flaws to perform a cross-site scripting (XSS) attack against victims using Certificate System's web interface. (CVE-2012-4543) Multiple denial of service flaws were found in the Red Hat Certificate System token processing. A Certificate System user could use these flaws to crash the Apache httpd web server child process, possibly interrupting the processing of other users' requests.
