CVE-2025-53015
📋 TL;DR
ImageMagick versions before 7.1.2-0 contain an infinite loop vulnerability when processing XMP files during conversion. This can cause denial of service through resource exhaustion. Any system using vulnerable ImageMagick versions for image processing is affected.
💻 Affected Systems
- ImageMagick
📦 What is this software?
Imagemagick by Imagemagick
⚠️ Risk & Real-World Impact
Worst Case
Complete system resource exhaustion leading to denial of service, potentially affecting availability of services using ImageMagick for image processing.
Likely Case
Process hangs or crashes when processing malicious XMP files, causing service disruption for applications relying on ImageMagick.
If Mitigated
Limited impact with proper input validation and resource limits in place, potentially causing only individual process failures.
🎯 Exploit Status
Exploitation requires ability to provide malicious XMP files to ImageMagick processing. No authentication needed if system processes untrusted files.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 7.1.2-0
Vendor Advisory: https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-vmhh-8rxq-fp9g
Restart Required: No
Instructions:
1. Update ImageMagick to version 7.1.2-0 or later. 2. For Linux: Use package manager (apt-get upgrade imagemagick, yum update imagemagick, etc.). 3. For source builds: Download latest from ImageMagick.org and recompile. 4. Verify update with 'convert --version'.
🔧 Temporary Workarounds
Disable XMP processing
allConfigure ImageMagick to disable XMP file format processing
Edit policy.xml: <policy domain="coder" rights="none" pattern="XMP" />
Resource limits
allSet resource limits to prevent complete system exhaustion
Edit policy.xml: <policy domain="resource" name="time" value="30"/>
Edit policy.xml: <policy domain="resource" name="memory" value="256MiB"/>
🧯 If You Can't Patch
- Implement strict input validation to reject or sanitize XMP files before processing
- Isolate ImageMagick processes with containerization or sandboxing to limit impact
🔍 How to Verify
Check if Vulnerable:
Run 'convert --version' and check if version is below 7.1.2-0Check Version:
convert --version | head -1Verify Fix Applied:
Run 'convert --version' and confirm version is 7.1.2-0 or higher📡 Detection & Monitoring
Log Indicators:
- ImageMagick processes consuming excessive CPU/time
- Process crashes or hangs during image conversion
- Repeated conversion failures for XMP files
Network Indicators:
- Unusual uploads of XMP files to image processing endpoints
- Increased resource usage on image processing servers
SIEM Query:
process_name:"convert" AND (cpu_usage:>90 OR duration:>300s)
