Description
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.
