3. Description:

Red Hat Identity Management (IdM) is a centralized authentication, identity
management, and authorization solution for both traditional and cloud-based

treats certificate revocation requests. An attacker logged in with the
'retrieve certificate' permission enabled could use this flaw to revoke
certificates, possibly triggering a denial of service attack.
(CVE-2016-5404)

This issue was discovered by Fraser Tweedale (Red Hat).
