Linux Distros 未修補弱點：CVE-2026-102270
medium Nessus Plugin ID 351364
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。- PyJWT 是 JSON Web 令牌標準的 Python 實作。在之前 2.14.0，PyJWT is_pem_format會受到影響，因為延遲的 PEM 規則運算式會大量回溯。當類似憑證的輸入包含重複的 BEGIN 標記而沒有相符的 END 標記時，就會發生這種情況。因此，is_pem_format在搜尋 PEM 結束標記時執行無限回溯。因此，攻擊者可能會造成大量 CPU 消耗。2.14.0 版已修正此問題。(CVE-2026-102270)
請注意，Nessus 依賴供應商報告的套件存在。
