マイクロソフトの不正ソフト対策エンジンに脆弱性


Microsoft社のマルウェアスキャンエンジンに深刻度の高い脆弱性が見つかり、修正プログラムが配布されています。「マルウェアスキャンエンジン」とは不正ソフト・コードを探知するシステムの中核部分で、このエンジンは「Windows Defender」や「Microsoft Security Essentials」などで使用されています。

オンデマンドによるファイルのスキャンはもちろん、リアルタイム保護を有効にしている場合は、ウェブサイトを閲覧したり、メールやインスタントメッセージを開いたタイミングでスキャンが行われるため、攻撃で狙われるおそれがある。(Security NEXTより引用)
とのことです。

修正プログラムは自動的にインストールされ、バージョンは「1.1.14405.2」へ更新されます。自動適用ですので作業は不要ですが、管理者の方はアップデート完了を確認しておいた方がよいでしょう。

  3. As of my last knowledge update in January 2022, I don't have any specific information about a vulnerability in Microsoft's anti-malware engine referred to as "4LINES." It's important to note that software vulnerabilities are not uncommon, and security updates are regularly released by software vendors to address them.

    If there is a specific vulnerability in Microsoft's anti-malware engine that has been identified since my last update, I recommend checking official Microsoft sources, such as the Microsoft Security Response Center (MSRC) website, for the latest information on security vulnerabilities and patches. You can also stay informed by subscribing to security mailing lists or following relevant security news sources.

    Remember, it's crucial to keep your security software up-to-date to protect your systems from potential threats. Always apply security patches and updates as soon as they become available.
