⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with system-level privileges, allowing complete compromise of affected devices
Likely Case
Application crash (denial of service) or limited memory corruption leading to unstable behavior
If Mitigated
Application crash without code execution if memory protections (ASLR, DEP) are properly implemented
🎯 Exploit Status
Exploitation requires crafting malicious PNG files and triggering their processing
