BUGTRAQ  ID: 108651
CVE(CAN) ID: CVE-2019-0973

Windows Installer是在Windows 2000时提出，作为微软操作系统中的安装程序开发标准的操作系统服务。它可以支持安装程序所需要的许多功能，并且可以支持交易式安装，当安装程序发现错误或问题时，可以将安装程序中所做的任何修改全部回溯为未变更的状态。

当Windows Installer无法正确清理输入导致不安全的库加载行为时，Windows Installer中存在一个特权提升漏洞。本地认证的攻击者可以使用提升的系统特权运行任意代码，即“Windows Installer特权提升漏洞”。

本地攻击者可以利用此问题以提升的权限执行任意代码。
