⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise if the integer overflow enables memory corruption that can be weaponized.
Likely Case
Application crash (denial of service) when processing malicious image files, potentially causing data loss in unsaved editing sessions.
If Mitigated
Limited impact if only trusted image sources are used and application runs with minimal privileges.
🎯 Exploit Status
Exploitation requires user interaction to open a malicious image file. No public exploit code is currently available.
