DLL preload vulnerability in McAfee Agent for Windows

A vulnerability in the preloading mechanism of specific dynamic link libraries in McAfee Agent for Windows prior to 5.7.3 could allow an authenticated, local attacker to perform a DLL preloading attack with unsigned DLLs. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system. This would result in the user gaining elevated permissions and being able to execute arbitrary code.

InstallBuilder for Qt Windows (versions prior to 20.7.0) installers look for plugins at a predictable location at initialization time, writable by non-admin users. While those plugins are not required, they are loaded if present, which could allow an attacker to plant a malicious library which could result in code execution with the security scope of the installer.
