CVE-2025-14425
📋 TL;DR
This vulnerability in GIMP allows remote attackers to execute arbitrary code by tricking users into opening malicious JP2 image files. The flaw exists in how GIMP handles JP2 file data without proper length validation, leading to heap buffer overflow. All GIMP users who open untrusted JP2 files are affected.
💻 Affected Systems
- GIMP (GNU Image Manipulation Program)
📦 What is this software?
Gimp by Gimp
⚠️ Risk & Real-World Impact
Worst Case
Full 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 affected system, with potential data exfiltration.
If Mitigated
Application crash (denial of service) if exploit fails or security controls prevent code execution.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file) but no authentication. ZDI has confirmed the vulnerability and likely has working exploit code.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: GIMP with commit cd1c88a0364ad1444c06536731972a99bd8643fd or later
Vendor Advisory: https://gitlab.gnome.org/GNOME/gimp/-/commit/cd1c88a0364ad1444c06536731972a99bd8643fd
Restart Required: Yes
Instructions:
1. Update GIMP through your distribution's package manager (apt, yum, dnf, etc.) or download latest version from gimp.org. 2. Restart GIMP after update. 3. Verify version includes the fix commit.
🔧 Temporary Workarounds
Disable JP2 file support
linuxRemove or disable JP2 file format plugin to prevent exploitation
mv /usr/lib/gimp/2.0/plug-ins/file-jp2* ~/backup/
mv /usr/lib64/gimp/2.0/plug-ins/file-jp2* ~/backup/
Block JP2 files at perimeter
allConfigure email/web filters to block .jp2 files
🧯 If You Can't Patch
- Implement application whitelisting to prevent unauthorized code execution
- Run GIMP in sandboxed environment or with reduced privileges
🔍 How to Verify
Check if Vulnerable:
Check if GIMP version predates commit cd1c88a0364ad1444c06536731972a99bd8643fdCheck Version:
gimp --versionVerify Fix Applied:
Verify GIMP version includes the fix commit or check that JP2 files no longer cause crashes📡 Detection & Monitoring
