CVE-2013-1416

Summary	The prep_reprocess_req function in do_tgs_req.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.10.5 does not properly perform service-principal realm referral, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted TGS-REQ request.

MIT Kerberos の鍵配布センタ (KDC) におけるサービス運用妨害 (DoS) の脆弱性

Title	MIT Kerberos の鍵配布センタ (KDC) におけるサービス運用妨害 (DoS) の脆弱性
Summary	MIT Kerberos 5 (別名 krb5) の鍵配布センタ (KDC) の do_tgs_req.c 内の prep_reprocess_req 関数は、サーバプリンシパルのレルム照会 (service-principal realm referral) を適切に実行しないため、サービス運用妨害 (NULL ポインタデリファレンスおよびデーモンクラッシュ) 状態にされる脆弱性が存在します。
Possible impacts	リモート認証されたユーザにより、巧妙に細工された TGS-REQ リクエストを介して、サービス運用妨害 (NULL ポインタデリファレンスおよびデーモンクラッシュ) 状態にされる可能性があります。
Solution	ベンダより正式な対策が公開されています。ベンダ情報を参照して適切な対策を実施してください。
