## Technical details

A heap-based buffer overflow exists in the OGWU file parser due to insufficient validation of user-supplied data length before copying to a heap buffer. The vulnerability requires user interaction (opening a file or visiting a webpage) but can be exploited to execute arbitrary code in the process context. The flaw has been patched by OriginLab.
