DLL Hijacking in LiveOn Meet and CanonNWCam Plugin Installers

The installers of LiveOn Meet Client for Windows (Downloader5Installer.exe and Downloader5InstallerForAdmin.exe) and the installers of Canon Network Camera Plugin (CanonNWCamPlugin.exe and CanonNWCamPluginForAdmin.exe) insecurely load Dynamic Link Libraries (DLLs). If a malicious DLL is placed at the same directory, the affected installer may load that DLL and execute its code with the privilege of the user invoking the installer.
