CVE-2025-1471
📋 TL;DR
This CVE describes a buffer overflow vulnerability in Eclipse OMR's z/OS atoe print functions. Attackers could exploit this to execute arbitrary code or cause denial of service. Affected systems are those running Eclipse OMR versions 0.2.0 to 0.4.0 on z/OS platforms.
💻 Affected Systems
- Eclipse OMR
📦 What is this software?
Omr by Eclipse
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or persistent backdoor installation.
Likely Case
Application crash or denial of service affecting availability of services using Eclipse OMR.
If Mitigated
Limited impact with proper input validation and memory protection mechanisms in place.
🎯 Exploit Status
Exploitation requires specific knowledge of z/OS environment and buffer overflow techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.5.0 and later
Vendor Advisory: https://gitlab.eclipse.org/security/cve-assignement/-/issues/55
Restart Required: No
Instructions:
1. Upgrade Eclipse OMR to version 0.5.0 or later. 2. Rebuild any applications using the patched OMR library. 3. Deploy updated applications to affected systems.
🔧 Temporary Workarounds
Input validation wrapper
z/OSImplement custom input validation for format strings passed to atoe print functions
Custom implementation required - no standard commands
🧯 If You Can't Patch
- Implement strict input validation for all user-supplied format strings
- Deploy memory protection mechanisms like ASLR and stack canaries
🔍 How to Verify
Check if Vulnerable:
Check Eclipse OMR version: omrversion -v and verify if between 0.2.0 and 0.4.0
Check Version:
omrversion -v
Verify Fix Applied:
Confirm version is 0.5.0 or later: omrversion -v | grep -E '0\.5\.|0\.6\.|0\.7\.'
