⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the Krita process, potentially leading to full system compromise if Krita runs with elevated privileges.
Likely Case
Application crash (denial of service) when opening malicious TGA files, with potential for limited code execution in some scenarios.
If Mitigated
Application crash without code execution if exploit fails or security controls (ASLR, DEP) are effective.
🎯 Exploit Status
Exploitation requires user interaction (opening a malicious file). No public exploit code has been identified as of the advisory date.
