セキュリティ問題を修正したsquidのアップデートパッケージがRed Hat Enterprise Linux 2.1、3、4、および5で利用可能になりました。
このアップデートは、レッドハットセキュリティ対策チームによって、深刻度「中(Moderate)」のセキュリティ問題と評価されています。
squidはWebクライアント用の高性能プロキシキャッシングサーバであり、FTP、gopher、およびHTTPデータオブジェクトをサポートしています。
キャッシュされたオブジェクトのHTTPヘッダをsquidがシステムメモリに保存する処理で欠陥が見つかりました。攻撃者がsquidで余計なメモリを使用し、キャッシュされた特定のオブジェクトの要求を処理するときにCPU使用率を引き上げることにより、サービス拒否を引き起こすことが可能です。(CVE-2007-6239)
squidのユーザは、この問題を解決するバックポートパッチを含む上記アップデートパッケージにアップグレードしてください。
