CVE-2025-52456
📋 TL;DR
A memory corruption vulnerability in the SAIL Image Decoding Library's WebP animation decoder allows remote code execution via specially crafted .webp files. When an integer overflow occurs during stride calculation, it leads to heap buffer overflow. Any application using SAIL Library v0.9.8 for WebP image processing is affected.
💻 Affected Systems
- SAIL Image Decoding Library
📦 What is this software?
Sail by Sail
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the application processing the malicious WebP file, potentially leading to full system compromise.
Likely Case
Application crash (denial of service) or limited code execution within the application context.
If Mitigated
Application crash without code execution if memory protections (ASLR, DEP) are effective.
🎯 Exploit Status
Exploitation requires convincing the application to load a malicious WebP file. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v0.9.9 or later
Vendor Advisory: https://talosintelligence.com/vulnerability_reports/TALOS-2025-2224
Restart Required: Yes
Instructions:
1. Check current SAIL Library version. 2. Update to v0.9.9 or later from official repository. 3. Rebuild any applications using the library. 4. Restart affected services.
🔧 Temporary Workarounds
Disable WebP animation processing
allConfigure applications to reject or skip WebP animation files if possible.
Application-specific configuration required
Input validation for WebP files
allImplement file validation to reject suspicious WebP files before processing.
Custom implementation required based on application
🧯 If You Can't Patch
- Implement strict file upload controls to prevent malicious WebP files from reaching vulnerable systems.
- Use application sandboxing or containerization to limit potential damage from exploitation.
🔍 How to Verify
Check if Vulnerable:
Check if SAIL Library v0.9.8 is installed and used by applications for WebP decoding.Check Version:
sail-config --version or check library files for version informationVerify Fix Applied:
Verify SAIL Library version is v0.9.9 or later and applications have been rebuilt with the updated library.📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing WebP files
- Memory access violation errors in application logs
Network Indicators:
- Unusual file uploads of WebP files to vulnerable endpoints
