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)
