CVE-2025-69204
📋 TL;DR
ImageMagick versions before 7.1.2-12 contain an integer overflow vulnerability in the WriteSVGImage function that can trigger a buffer overflow. This allows attackers to cause denial of service (DoS) by crashing the application when processing malicious SVG images. 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
Remote code execution if the buffer overflow can be controlled to execute arbitrary code, though the advisory only confirms DoS.
Likely Case
Denial of service through application crash when processing malicious SVG files.
If Mitigated
Minimal impact if proper input validation and sandboxing are implemented.
🎯 Exploit Status
Exploitation requires crafting a malicious SVG file with specific attributes to trigger the integer overflow.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 7.1.2-12
Vendor Advisory: https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-hrh7-j8q2-4qcw
Restart Required: Yes
Instructions:
1. Update ImageMagick to version 7.1.2-12 or later using your package manager. 2. For Linux: 'sudo apt update && sudo apt upgrade imagemagick' (Debian/Ubuntu) or 'sudo yum update imagemagick' (RHEL/CentOS). 3. Restart any services using ImageMagick.
🔧 Temporary Workarounds
Disable SVG processing
linuxRemove or disable SVG support in ImageMagick configuration to prevent processing of SVG files.
Edit /etc/ImageMagick-7/policy.xml and add: <policy domain="coder" rights="none" pattern="SVG" />
🧯 If You Can't Patch
- Implement strict input validation to reject malformed SVG files before processing.
- Run ImageMagick in a sandboxed environment with limited privileges to contain potential crashes.
🔍 How to Verify
Check if Vulnerable:
Check ImageMagick version with 'convert --version' or 'magick --version' and verify it's below 7.1.2-12.Check Version:
convert --version | head -1Verify Fix Applied:
After updating, run 'convert --version' or 'magick --version' and confirm version is 7.1.2-12 or higher.📡 Detection & Monitoring
Log Indicators:
- Application crashes or segmentation faults in ImageMagick processes when handling SVG files.
- Error messages related to buffer overflows or memory corruption in system logs.
Network Indicators:
- Unusual uploads of SVG files to web applications using ImageMagick.
