CVE-2025-1470
📋 TL;DR
This vulnerability in Eclipse OMR versions up to 0.4.0 allows NULL pointer dereference crashes when z/OS atoe functions fail to allocate memory. It affects systems running Eclipse OMR on z/OS platforms. The issue was fixed in version 0.5.0.
💻 Affected Systems
- Eclipse OMR
📦 What is this software?
Omr by Eclipse
⚠️ Risk & Real-World Impact
Worst Case
Application crash leading to denial of service for dependent services
Likely Case
Application instability or crashes during memory-intensive operations
If Mitigated
Graceful error handling with no service disruption
🎯 Exploit Status
Requires ability to trigger memory allocation failures on z/OS systems
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.5.0 and later
Vendor Advisory: https://gitlab.eclipse.org/security/cve-assignement/-/issues/54
Restart Required: Yes
Instructions:
1. Upgrade Eclipse OMR to version 0.5.0 or later
2. Rebuild any applications using OMR libraries
3. Restart affected services
🔧 Temporary Workarounds
Memory limit monitoring
z/OSMonitor and prevent memory exhaustion on z/OS systems
# Use z/OS system monitoring tools to track memory usage
# Set memory limits for OMR processes
🧯 If You Can't Patch
- Implement robust monitoring for memory allocation failures on z/OS
- Isolate vulnerable systems from production workloads
🔍 How to Verify
Check if Vulnerable:
Check OMR version and confirm z/OS platform: omrversion -vCheck Version:
omrversion -vVerify Fix Applied:
Verify version is 0.5.0 or higher and check for NULL pointer handling in atoe function calls📡 Detection & Monitoring
Log Indicators:
