There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A flaw was found in GStreamer's gst-plugins-base MicroDVD subtitle parser. When processing a specially
    crafted subtitle file, the parser may dereference a NULL pointer, causing the application to crash when a
    user opens or plays media with a malformed MicroDVD (.sub) subtitle file. (CVE-2026-119842)

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。

  - 在 GStreamer 的 gst-plugins-base MicroDVD 字幕剖析器中發現一個缺陷。處理特製的字幕檔時，剖析器可能會取消參照 NULL 指標，導致當使用者開啟或播放具有格式錯誤的 MicroDVD （.sub） 字幕檔的媒體時，應用程式當機。（CVE-2026-119842）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 在 GStreamer 的 gst-plugins-base MicroDVD 字幕解析器中发现一个缺陷。当处理特别构建的副标题文件时，解析器可能会取消引用空指针，从而在用户打开或播放包含畸形 MicroDVD （.sub） 字幕文件的媒体时造成该应用程序崩溃。（CVE-2026-119842）

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - GStreamer の gst-plugins-base MicroDVD 字幕パーサーで欠陥が見つかりました。特別に細工された字幕ファイルを処理する際、パーサーが NULL ポインターを逆参照することがあるため、ユーザーが無効な形式の MicroDVD(.sub)字幕ファイルのあるメディアを開いたり再生したりすると、アプリケーションがクラッシュする可能性があります。(CVE-2026-119842)

Nessus は、ベンダーから報告されたパッケージの存在に依存していることに注意してください。
