Technical details
The vulnerability is a memory corruption flaw in OriginLab Origin Viewer's OGW project file parser. The parser fails to properly validate user-supplied data in crafted OGW files, leading to out-of-bounds memory access or heap corruption. Exploitation requires local attack vector (file access) and user interaction—the victim must open a malicious OGW file in Origin Viewer. Successful exploitation results in arbitrary code execution with the privileges of the current user. A patch is available in Origin Viewer version 10.4.0.25 or later.
