When a category lookup agent is used in a per-request policy for SWG and it uses the subject.cn as an input, agent_category_lookup assumes that the subject always contains a CN. When a CN is not present in the subject, the parsing involved will dereference invalid memory and cause a crash.
Traffic disrupted while tmm restarts.
Access a server which has no CN in the subject.cn
