Technical details
The vulnerability is an out-of-bounds write flaw in OriginLab Origin Viewer's OPJ file parser. The root cause is insufficient validation of user-supplied data during the parsing of OPJ project files, allowing an attacker to write past the end of an allocated data structure. The attack requires user interaction: a target must open a malicious OPJ file, typically via direct file opening or a deceptive link. An attacker can leverage this memory corruption to achieve arbitrary code execution in the context of the current process. OriginLab has patched this vulnerability; users should update to Origin Viewer 10.4.0.25 or later.
