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。

  - f2fs：修复以在恢复期间对目标 blkaddr 进行健全性检查 正如 Wenqing Liu 在 bugzilla 中报告的：

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 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。

  - f2fs：修正在復原期間對目的地 blkaddr 進行健全性檢查 正如 Wenqing Liu 在 bugzilla 中報告的那樣：

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

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。

  - f2fs:復元中の宛先 blkaddr でのサニティチェックの実行を修正します。 Wenqing Liu 氏が bugzilla で報告しているように:

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。
