An input validation error was found in Red Hat Certificate System's handling of client provided certificates before 8.1.20-1. If the certreq field is not present in a certificate an assertion error is triggered causing a denial of service.

The token processing system (pki-tps) in Red Hat Certificate System (RHCS) before 8.1.3 allows remote attackers to cause a denial of service (Apache httpd web server child process restart) via certain unspecified empty search fields in a user certificate search query.

The token processing system (pki-tps) in Red Hat Certificate System (RHCS) before 8.1.3 does not properly handle interruptions of token format operations, which allows remote attackers to cause a denial of service (NULL pointer dereference and Apache httpd web server child process crash) via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in Red Hat Certificate System (RHCS) before 8.1.3 allow remote attackers to inject arbitrary web script or HTML via the (1) pageStart or (2) pageSize to the displayCRL script, or (3) nonce variable to the profileProcess script.

Red Hat Certificate System (RHCS) before 8.1.1 and Dogtag Certificate System does not properly check certificate revocation requests made through the web interface, which allows remote attackers with permissions to revoke end entity certificates to revoke the Certificate Authority (CA) certificate.

Multiple cross-site scripting (XSS) vulnerabilities in Red Hat Certificate System (RHCS) before 8.1.1 and Dogtag Certificate System allow remote attackers to inject arbitrary web script or HTML via unspecified parameters to the (1) System Agent or (2) End Entity pages.
