CVE-2017-7509
If the certreq field is not present in a certificate an assertion error is triggered causing a denial of service.
Does this matter?
Lower severity and a low EPSS score (0.73%). Track it; it rarely justifies an emergency change on its own.
Description
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.
