Debian セキュリティ勧告
DSA-1719-1 gnutls13 -- 設計ミス
- 報告日時:
- 2009-02-10
- 影響を受けるパッケージ:
- gnutls13
- 危険性:
- あり
- 参考セキュリティデータベース:
- Debian バグ追跡システム: バグ 505360.
Mitre の CVE 辞書: CVE-2008-4989. - 詳細:
-
Martin von Gagern さんにより、TLS/SSL プロトコル実装 GNUTLS が自己署名を持 つ証明書が信用できる証明書として設定されている場合に、X.509 証明書チェイン の処理を誤っていることが発見されました。この結果、偽サーバの証明書を純正な ものとして扱う可能性があります (CVE-2008-4989)。
これに加えて、今回の更新では X.509v1 証明書のチェックを厳格にしているため、 以前は GNUTLS が受け入れていた証明書が拒絶される場合があります。これは、証 明書チェイン処理で、アプリケーションから明示的に要求されない限り、GNUTLS が X.509v1 証明書を認識しないように変更されたためです。
安定版 (stable) ディストリビューション (etch) では、この問題はバージョン 1.4.4-3+etch3 で修正されています。
不安定版 (unstable) ディストリビューション (sid) では、この問題はバージョ ン 2.4.2-3 で修正されています。
直ぐに gnutls13 パッケージをアップグレードすることを勧めます。
- 修正:
-
Debian GNU/Linux 4.0 (etch)
