1. 修復的CVE CVE-2018-10196 Graphviz（Graph Visualization Software）是美國AT&T實驗室研發的一套用于繪制DOT語言腳本所描述的圖形的開源繪圖工具。 Graphviz 2.40.1版本中的dotgen庫的lib/dotgen/conc.c文件的‘rebuild_vlists’函數存在安全漏洞。遠程攻擊者可借助特制的文件利用該漏洞造成拒絕服務（空指針逆向引用和崩潰）。 CVE-2020-18032 Graphviz是一套開源的圖形可視化軟件。該軟件主要用于繪制DOT語言腳本中指定的圖形。Graphviz Graph Visualization Tools 存在安全漏洞，該漏洞允許遠程攻擊者執行任意代碼或通過加載一個制作好的文件到“lib common shapes.c”組件導致拒絕服務(應用程序崩潰)。 CVE-2019-11023 Graphviz是一套開源的圖形可視化軟件。該軟件主要用于繪制DOT語言腳本中指定的圖形。Graphviz 2.39.20160612.1140版本中的libcgraph.a靜態鏈接庫的cgraphobj.c文件的‘agroot()’函數存在空指針逆向引用漏洞，該漏洞源于網絡系統或產品的代碼開發過程中存在設計或實現不當的問題。 2. 受影響的操作系統及軟件包 ·銀河麒麟桌面操作系統V10 x86_64 架構：
