## Technical details

The vulnerability is an out-of-bounds write (stack or heap buffer overflow) in the OPJ file parser caused by insufficient validation of user-supplied data. Exploitation requires user interaction (opening a malicious OPJ file), but once triggered, allows arbitrary code execution in the context of the viewer process.
