Debian DLA-3484-1: firefox-esr - LTS セキュリティ更新

high Nessus プラグイン ID 178041

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 10 ホストには、dla-3484 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。

- HTTPS 経由で WebRTC 接続を作成する際に、攻撃者が Use After Free (メモリ解放後使用) 状態を発生させる可能性がありました。
この脆弱性の影響を受けるのは、Firefox < 115、Firefox ESR < 102.13、Thunderbird < 102.13 です。(CVE-2023-37201)

- スクリプト化されたプロキシをラッピングするクロスコンパートメントラッパーにより、他のコンパートメントからのオブジェクトがメインコンパートメントに保存され、Use After Free (メモリ解放後使用) が発生する可能性がありました。この脆弱性の影響を受けるのは、Firefox < 115、Firefox ESR < 102.13、Thunderbird < 102.13 です。(CVE-2023-37202)

- Web サイトが、mailto URL などの外部プログラムによって処理されるスキームを伴う URL を使用することで、フルスクリーン通知を覆い隠す可能性があります。これにより、ユーザーの混乱やなりすまし攻撃が発生する可能性がありました。この脆弱性の影響を受けるのは、Firefox < 115、Firefox ESR < 102.13、Thunderbird < 102.13 です。
(CVE-2023-37207)

- Diagcab ファイルを開く際、Firefox はこれらのファイルに悪意のあるコードが含まれている可能性があることをユーザーに警告しませんでした。
この脆弱性の影響を受けるのは、Firefox < 115、Firefox ESR < 102.13、Thunderbird < 102.13 です。(CVE-2023-37208)

- Firefox 114、Firefox ESR 102.12、および Thunderbird 102.12 に存在するメモリの安全性のバグ。これらのバグの一部にはメモリ破損の証拠が示されており、当社では、手間をかけることにより、これらの一部が悪用され、任意のコードが実行される可能性があると推測しています。この脆弱性の影響を受けるのは、Firefox < 115、Firefox ESR < 102.13、Thunderbird < 102.13 です。(CVE-2023-37211)

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 10 buster では、これらの問題はバージョン 102.13.0esr-1~deb10u1 で修正されています。
