CVE-2025-68618
📋 TL;DR
ImageMagick versions before 7.1.2-12 contain a denial-of-service vulnerability when processing malicious SVG files. Attackers can cause the application to crash by submitting specially crafted SVG images. This affects any system or application that uses ImageMagick to process user-uploaded images.
💻 Affected Systems
- ImageMagick
📦 What is this software?
Imagemagick by Imagemagick
⚠️ Risk & Real-World Impact
Worst Case
Complete service disruption where ImageMagick processes crash repeatedly, potentially affecting availability of image processing services.
Likely Case
Temporary service interruption when processing malicious SVG files, requiring process restart.
If Mitigated
Minimal impact with proper input validation and process isolation in place.
🎯 Exploit Status
Exploitation requires only the ability to submit an SVG file to an affected ImageMagick instance.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 7.1.2-12
Vendor Advisory: https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-p27m-hp98-6637
Restart Required: Yes
Instructions:
1. Update ImageMagick to version 7.1.2-12 or later. 2. For Linux systems: Use package manager (apt-get upgrade imagemagick, yum update imagemagick, etc.). 3. For source installations: Download latest version from ImageMagick.org and recompile. 4. Restart all services using ImageMagick.
🔧 Temporary Workarounds
Disable SVG processing
allRemove or disable SVG support in ImageMagick policy.xml
Edit /etc/ImageMagick-7/policy.xml or similar policy file
Add or modify: <policy domain="delegate" rights="none" pattern="SVG" />
Input validation
allReject SVG files at application level before passing to ImageMagick
Implement file type validation in your application code
Check file extensions and MIME types before processing
🧯 If You Can't Patch
- Implement strict input validation to reject or sanitize SVG files before processing
- Isolate ImageMagick processes with resource limits and automatic restart mechanisms
🔍 How to Verify
Check if Vulnerable:
Check ImageMagick version with: convert --version | grep VersionCheck Version:
convert --version | grep VersionVerify Fix Applied:
Verify version is 7.1.2-12 or higher: convert --version | grep -q '7.1.2-12' && echo 'Patched' || echo 'Vulnerable'📡 Detection & Monitoring
Log Indicators:
