DSA-1896-1 opensaml, shibboleth-sp -- 複数の脆弱性

報告日時:
2009-09-28
影響を受けるパッケージ:
opensaml, shibboleth-sp
危険性:
あり
参考セキュリティデータベース:
現時点では、その他の外部参考セキュリティデータベースはありません。
詳細:

Opensaml および Shibboleth 1.x で使用している shibboleth-sp パッケージに、 複数の問題が発見されました。

  • Chris Ries さんにより、細工された URL デコードの際にクラッシュ (そして任 意のコードの実行の可能性) に繋がる場合があることが発見されました。

  • Ian Young さんにより、証明書名に埋め込まれた NULL 文字が正しく処理されて おらず、PKIX 信用認証機構を用いている設定で偽装 (impersonation) 攻撃が可 能であることが発見されました。

  • SAML メタデータ処理で、鍵の使用制限の制約が誤って無視されています。

旧安定版 (oldstable) ディストリビューション (etch) では、これらの問題は バージョン 1.3f.dfsg1-2+etch1 の shibboleth-sp パッケージと、バージョン 1.1a-2+etch1 の Opensaml パッケージで修正されています。

安定版 (stable) ディストリビューション (lenny) では、これらの問題はバー ジョン 1.3.1.dfsg1-3+lenny1 の shibboleth-sp パッケージと、バージョン 1.1.1-2+lenny1 の Opensaml パッケージ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) には Shibboleth 1.x パ ッケージは収録されていません。

この更新では、効果を得るためには影響のあるサービス (主に Apache) の再起 動が必要です。

直ぐに Shibboleth 1.x 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)
