Debian セキュリティ勧告
DSA-143-1 krb5 -- 整数オーバフロー
- 報告日時:
- 2002-08-05
- 影響を受けるパッケージ:
- krb5
- 危険性:
- あり
- 参考セキュリティデータベース:
- (SecurityFocus の) Bugtraq データベース: BugTraq ID 5356.
Mitre の CVE 辞書: CVE-2002-0391.
CERT の脆弱性リスト、勧告および付加情報: VU#192995. - 詳細:
-
整数オーバフローによるバグが、SunRPC 由来の Kerberos 5 認証システムで用いている RPC ライブラリで発見されました。このバグにより、KDC ホストを攻撃して不正に root 権限を取得することができます。 現在、攻撃者はこの攻撃に成功するためには、kadmin デーモンにて認証を得る必要があると考えられていますが、現在のところ攻撃手法は知られていません。
この問題は、現安定版 (stable) のバージョン 1.2.4-5woody1、及び不安定版 (unstable) ではバージョン 1.2.5-2 で修正されています。旧安定版 (stable) の potato には krb5 パッケージは収録されていないため、この脆弱性を持ち ません。
すぐに kerberos パッケージをアップグレードすることを勧めます。
