CVE-2025-46407
📋 TL;DR
A memory corruption vulnerability in SAIL Image Decoding Library's BMPv3 palette decoding allows remote code execution when processing malicious .bmp files. This affects any application using SAIL v0.9.8 for image processing. Attackers can exploit this by tricking users or systems into loading crafted BMP images.
💻 Affected Systems
- SAIL Image Decoding Library
📦 What is this software?
Sail by Sail
⚠️ Risk & Real-World Impact
Worst Case
Full remote code execution with system compromise, data theft, and lateral movement within the network.
Likely Case
Application crash leading to denial of service, with potential for limited code execution depending on exploit reliability.
If Mitigated
Application crash without code execution if exploit fails or mitigations like ASLR/DEP are effective.
🎯 Exploit Status
Exploitation requires convincing the target to process a malicious BMP file. No public exploit code is available at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v0.9.9 or later
Vendor Advisory: https://talosintelligence.com/vulnerability_reports/TALOS-2025-2215
Restart Required: Yes
Instructions:
1. Check current SAIL library version
2. Update to v0.9.9 or later
3. Recompile any applications using SAIL
4. Restart affected services
🔧 Temporary Workarounds
Disable BMP processing
allConfigure applications to reject or not process BMP files
Application-specific configuration required
Input validation
allImplement strict file type validation before passing to SAIL library
Implement file signature checking before processing
🧯 If You Can't Patch
- Implement network segmentation to isolate systems using SAIL
- Deploy application allowlisting to prevent unauthorized code execution
🔍 How to Verify
Check if Vulnerable:
Check if SAIL library version is 0.9.8 in application dependencies or linked librariesCheck Version:
ldd <application> | grep sail or check package manager for sail versionVerify Fix Applied:
Verify SAIL library version is 0.9.9 or later and test BMP file processing functionality📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing BMP files
- Memory access violation errors in application logs
- Unusual process spawning after image processing
Network Indicators:
- Unexpected outbound connections from image processing services
- Large number of BMP file uploads to vulnerable endpoints
