## Description

A vulnerability was found in ipa before 4.4. IdM's ca-del, ca-disable, and
ca-enable commands did not properly check the user's permissions while
modifying CAs in Dogtag. An authenticated, unauthorized attacker could use
this flaw to delete, disable, or enable CAs causing various denial of
service problems with certificate issuance, OCSP signing, and deletion of
secret keys.
