Red Hat Enterprise Linux: null pointer dereference
No fix yet
A flaw was found in the ipa-enrollment SLAPI plugin. A remote authenticated client can exploit a null pointer dereference vulnerability by sending a malformed Lightweight Directory Access Protocol (LDAP) extended operation. By omitting the request value for the JOIN_OID in the ipa-enrollment extended operation, an attacker can trigger a server crash, potentially causing a denial of service.
