Debian DLA-2971-1:firefox-esr - LTS セキュリティ更新

high Nessus プラグイン ID 159586

概要

リモートのDebianホストにセキュリティ関連の更新プログラムがありません。

説明

リモートの Debian 9 ホストには、dla-2971 のアドバイザリに記載された複数の脆弱性の影響を受けるパッケージがインストールされています。

- regex は、Rust 言語用の正規表現の実装です。regex crate は、信頼できない正規表現によって引き起こされるサービス拒否攻撃、または信頼できる正規表現に一致する信頼できない入力を防ぐ作り込みの緩和機能を備えています。これらの (調整可能な) 緩和策は、攻撃を防ぐための適切なデフォルトをすでに提供しています。この保証は文書化されており、クレートの API の一部と見なされています。残念ながら、信頼できない正規表現が解析中に任意の時間がかかることを防ぐために設計された緩和にバグが発見されました。このような緩和をバイパスする正規表現を作成することが可能です。これにより、特別に細工された正規表現を、ユーザーが制御する信頼できない正規表現を受け入れるサービスに送信することで、サービス拒否攻撃を実行できます。1.5.4以前のすべてのバージョンの正規表現クレートが、この問題の影響を受けます。修正には、正規表現 1.5.5からに含まれます。ユーザー制御の正規表現を受け入れるすべてのユーザーは、最新バージョンの正規表現にすぐにアップグレードすることが推奨されます。残念ながら、この脆弱性を悪用して細工される可能性のある事実上無限の正規表現があるため、問題のある正規表現の修正セットはありません。
このため、既知の問題のある正規表現を拒否することは推奨しません。(CVE-2022-24713)

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションの自己報告されたバージョン番号にのみ依存しています。

ソリューション

firefox-esr パッケージをアップグレードしてください。

Debian 9 Stretch では、これらの問題はバージョン 91.8.0esr-1~deb9u1 で修正されています。
