Check Point Endpoint Security Client for Windows, with Anti-Malware blade installed, before version E81.00, tries to load a non-existent DLL during an update initiated by the UI. An attacker with administrator privileges can leverage this to gain code execution within a Check Point Software Technologies signed binary, where under certain circumstances may cause the client to terminate.
Executing commands or loading libraries from an untrusted source or in an untrusted environment can cause an application to execute malicious commands (and payloads) on behalf of an attacker.
