CVE-2025-55154
📋 TL;DR
This vulnerability in ImageMagick allows integer overflow during PNG/MNG image processing, leading to memory corruption. Attackers can exploit this by crafting malicious images to potentially execute arbitrary code or cause denial of service. Any system using vulnerable ImageMagick versions to process untrusted images is affected.
💻 Affected Systems
- ImageMagick
📦 What is this software?
Imagemagick by Imagemagick
Imagemagick by Imagemagick
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the ImageMagick process, potentially leading to full system compromise.
Likely Case
Denial of service through application crashes or memory corruption leading to unstable behavior.
If Mitigated
Limited impact if proper input validation and sandboxing are implemented, though crashes may still occur.
🎯 Exploit Status
Exploitation requires crafting a malicious PNG/MNG image file, but no public proof-of-concept has been released yet.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.9.13-27 or 7.1.2-1
Vendor Advisory: https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-qp29-wxp5-wh82
Restart Required: Yes
Instructions:
1. Identify ImageMagick version using 'convert --version' or 'magick --version'. 2. Update via package manager: 'apt update && apt upgrade imagemagick' (Debian/Ubuntu) or 'yum update imagemagick' (RHEL/CentOS). 3. Restart any services using ImageMagick. 4. Verify update with version check.
🔧 Temporary Workarounds
Disable PNG/MNG processing
allRemove PNG and MNG support from ImageMagick policy.xml to prevent processing of vulnerable formats
Edit /etc/ImageMagick-6/policy.xml or /etc/ImageMagick-7/policy.xml
Add: <policy domain="coder" rights="none" pattern="PNG" />
Add: <policy domain="coder" rights="none" pattern="MNG" />
🧯 If You Can't Patch
- Implement strict input validation to reject suspicious PNG/MNG files before processing
- Run ImageMagick in a sandboxed environment with limited privileges and resource constraints
🔍 How to Verify
Check if Vulnerable:
Run 'convert --version' or 'magick --version' and check if version is below 6.9.13-27 (for ImageMagick 6) or below 7.1.2-1 (for ImageMagick 7)Check Version:
convert --version 2>/dev/null || magick --version 2>/dev/nullVerify Fix Applied:
Confirm version is 6.9.13-27 or higher (ImageMagick 6) or 7.1.2-1 or higher (ImageMagick 7) using version check command📡 Detection & Monitoring
Log Indicators:
- ImageMagick process crashes or segmentation faults
- Unusual memory usage patterns in image processing services
- Failed image conversion attempts with specific PNG/MNG files
Network Indicators:
- Unusually large PNG/MNG file uploads to web applications
- Multiple failed image processing requests from single source
SIEM Query:
source="*imagemagick*" AND (event="segmentation fault" OR event="crash" OR memory_usage>threshold)
