CVE-2025-60751
📋 TL;DR
CVE-2025-60751 is a stack-based buffer overflow vulnerability in GeographicLib's GeoConvert DMS::InternalDecode function. Attackers can exploit this by providing specially crafted DMS (degrees-minutes-seconds) coordinate strings, potentially leading to arbitrary code execution. This affects any application using GeographicLib 2.5 for geographic coordinate conversions.

⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with the privileges of the application using GeographicLib, potentially leading to complete system compromise.
Likely Case
Application crash (denial of service) or limited memory corruption leading to unstable behavior.
If Mitigated
Application crash with no code execution if modern security protections (ASLR, stack canaries) are effective.
🎯 Exploit Status
Proof-of-concept code is publicly available on GitHub. Exploitation requires understanding of DMS coordinate format and buffer overflow techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: GeographicLib 2.6 or later
Vendor Advisory: https://github.com/geographiclib/geographiclib/issues/43
Restart Required: Yes
Instructions:
1. Download GeographicLib 2.6 or later from the official repository. 2. Replace the vulnerable library files. 3. Recompile any applications using GeographicLib. 4. Restart affected services.
🔧 Temporary Workarounds
Input Validation for DMS Coordinates
allImplement strict validation and sanitization of DMS coordinate strings before passing to GeographicLib functions.
Disable DMS Parsing
allIf possible, disable DMS coordinate parsing functionality and use alternative coordinate formats.
🧯 If You Can't Patch
- Implement network segmentation to isolate systems using GeographicLib from untrusted networks.
- Deploy application-level firewalls or WAF rules to filter suspicious DMS coordinate patterns.
🔍 How to Verify
Check if Vulnerable:
Check if GeographicLib version 2.5 is installed using package manager or by checking library version.Check Version:
geoconvert --version 2>/dev/null || dpkg -l | grep geographiclib || rpm -qa | grep geographiclibVerify Fix Applied:
Verify GeographicLib version is 2.6 or later and test DMS coordinate parsing functionality.📡 Detection & Monitoring
