Linux Distros 未修補弱點：CVE-2026-93653
medium Nessus Plugin ID 348227
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，廠商表示將不會修補。說明
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 Poppler 的 Splash 後端發現拒絕服務缺陷。具有接近 int32 邊界的平鋪模式幾何圖形的特製 PDF 可能會導致 SplashOutputDev：：tilingPatternFill 計算攻擊者控制的重複計數，該計數會在模式填充掃描行常式中驅動過長的迴圈，而無需對應的記憶體配置。攻擊者可利用此弱點，方法是向透過 Poppler 的 Splash 後端呈現惡意 PDF 的應用程式提供惡意 PDF，導致轉譯程序在攻擊者控制的延長持續時間內消耗 100% CPU。（CVE-2026-93653）
請注意，Nessus 的判定取決於廠商所報告的套件是否存在。
