CVE-2025-10924
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code by tricking users into opening malicious FF files in GIMP. The integer overflow during file parsing enables buffer overflow leading to remote code execution. All GIMP users who open untrusted FF files are affected.
💻 Affected Systems
- GIMP (GNU Image Manipulation Program)
📦 What is this software?
Gimp by Gimp
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining the same privileges as the GIMP user, potentially leading to data theft, ransomware deployment, or lateral movement.
Likely Case
Local privilege escalation or malware installation on the user's system when opening a malicious FF file from email or downloads.
If Mitigated
Limited impact if user runs GIMP with minimal privileges and doesn't open untrusted files.
🎯 Exploit Status
Requires user interaction to open malicious file. Exploit development requires understanding of FF file format and GIMP's parsing logic.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version containing the fix from merge request 2448
Vendor Advisory: https://gitlab.gnome.org/GNOME/gimp/-/merge_requests/2448
Restart Required: No
Instructions:
1. Update GIMP to latest version from official repositories. 2. On Linux: Use package manager (apt, yum, dnf). 3. On Windows/macOS: Download from gimp.org. 4. Verify update applied.
🔧 Temporary Workarounds
Disable FF file support
linuxRemove or rename FF file plugin to prevent parsing
mv /usr/lib/gimp/2.0/plug-ins/file-ff /usr/lib/gimp/2.0/plug-ins/file-ff.disabled
Run with reduced privileges
allRun GIMP as non-admin user to limit exploit impact
🧯 If You Can't Patch
- Block FF files at network perimeter/email gateway
- Educate users to never open FF files from untrusted sources
🔍 How to Verify
Check if Vulnerable:
Check GIMP version and compare against patched version from merge request 2448Check Version:
