Debian DLA-1392-1：linux 安全性更新
high Nessus Plugin ID 110314
語系：
概要
遠端 Debian 主機缺少一個安全性更新。說明
在 Linux 核心中發現數個可導致拒絕服務的弱點。CVE-2018-1093 Wen Xu 報告特製的 ext4 檔案系統映像可能在 ext4_valid_block_bitmap() 函式中觸發超出邊界讀取。有權掛載任意檔案系統的本機使用者可利用此弱點造成拒絕服務。CVE-2018-1130 syzbot 軟體發現 sendmsg() 的 DCCP 實作未檢查通訊端狀態，可能導致 NULL 指標解除參照。本機使用者可利用此缺陷造成拒絕服務 (當機)。CVE-2018-8897 Everdox Tech LLC 的 Nick Peterson 發現被 MOV SS 或 POP 延遲的 #DB 例外狀況未正確處理，導致無權限的使用者損毀核心並造成拒絕服務。CVE-2018-10940 Dan Carpenter 報告 cdrom 驅動程式未正確驗證 CDROM_MEDIA_CHANGED ioctl 的參數。具有 cdrom 裝置存取權的使用者可利用此弱點造成拒絕服務 (當機)。針對 Debian 7「Wheezy」，這些問題已在 3.2.102-1 版本中修正。此版本也包含上游版本 3.2.102 的錯誤修正，包含版本 3.2.101 中 SCTP 實作的迴歸修正。建議您升級 linux 套件。注意：Tenable Network Security 已直接從 DLA 安全性公告擷取前置描述區塊。Tenable 已盡量在不造成其他問題的前提下，嘗試自動清理並將其格式化。解決方案
升級受影響的套件。另請參閱
