Linux Distros 未修補弱點：CVE-2026-92707
medium Nessus Plugin ID 367354
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。- MessagePack for C# 是 C# 的 MessagePack 序列化程式。在 2.5.303 和 3.1.9之前，透過 PrimitiveObjectFormatter 將攻擊者控制的 MessagePack 資料還原序列化為 System.Object 可能會導致過多的記憶體配置。格式化程式會在設定的物件圖形深度限制拒絕輸入之前，從每個宣告的陣列長度配置一個 object[]，而巢狀陣列標頭可以重複使用相同的尾端未讀取位元組來滿足每個標頭長度驗證。因此，相對較小的有效負載可以同時使許多大型陣列保持活動狀態。當攻擊者可以重複提交此類資料時，配置可能會造成嚴重的受管理堆積壓力、過多的記憶體回收、處理程序終止或服務遺失。曝險需要應用程式透過受影響的格式化程式路徑還原序列化不受信任的數據，並允許重複攻擊者控制的提交，例如具有物件參數和已啟用 AddMessagePackProtocol（） 的可連線 ASP.NET Core SignalR 中樞方法。此問題已在版本 2.5.303 和 3.1.9中修正。
