critical Nessus プラグイン ID 168857
Language:
概要
リモートの Debian ホストに 1 つまたは複数の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-3241 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。- コンテンツプロセスを侵害した攻撃者が、サンドボックスを部分的に回避して、クリップボード関連の IPC メッセージを介して任意のファイルを読み取る可能性があります。このバグの影響を受けるのは、Linux 向けの Thunderbird のみです。その他のオペレーティングシステムは影響を受けません。(CVE-2022-46872)
- 長いファイル名のファイルは、有効な拡張子を削除するためにファイル名が切り捨てられ、悪意のある拡張子がそのまま残される可能性があります。これにより、ユーザーの混乱や悪意のあるコードの実行が引き起こされる可能性があります。(CVE-2022-46874)
- Mozilla 開発者の Randell Jesup 氏、Valentin Gosu 氏、Olli Pettay 氏および Mozilla Fuzzing Team は、Firefox 107 と Firefox ESR 102.5に存在するメモリ安全性のバグを報告しました。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、十分な労力をもってすればこれらの一部を悪用し、任意のコードを実行することが可能であると推測しています。(CVE-2022-46878)
- tex ユニットに関連したチェックの欠如によりメモリ解放後使用 (Use After Free) が発生し、悪用可能なクラッシュを引き起こす可能性がありました。
(CVE-2022-46880)
- WebGL の最適化が不適切な場合があり、メモリ破損や悪用可能なクラッシュを引き起こす可能性がありました。(CVE-2022-46881)
- WebGL 拡張のメモリ解放後使用 (Use After Free) により、悪用可能なクラッシュを引き起こす可能性がありました。(CVE-2022-46882)
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 102.6.0esr-1~deb10u1 で修正されています。
