漏洞描述

LibreOffice是文档基金会（The Document Foundation，TDF）的一套开源的办公软件套件。该产品包含Writer（文本文档）、Calc（电子表格）和Impress（演示文稿）等应用程序。 LibreOffice 6.2.7之前的6.2版本和6.3.1之前的6.3版本中存在安全漏洞。攻击者可利用该漏洞执行任意的python命令。

LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can execute arbitrary python commands contained with the document it is launched from. LibreOffice also has a feature where documents can specify that pre-installed scripts can be executed on various document script events such as mouse-over, etc. Protection was added to block calling LibreLogo from script event handers. However a Windows 8.3 path equivalence handling flaw left LibreOffice vulnerable under Windows that a document could trigger executing LibreLogo via a Windows filename pseudonym. This issue affects: Document Foundation LibreOffice 6.2 versions prior to 6.2.7; 6.3 versions prior to 6.3.1.
