7.8 HIGH

📋 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

Products:
  • Eclipse OMR
Versions: 0.2.0 to 0.4.0
Operating Systems: z/OS
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects z/OS platforms; other operating systems are not vulnerable.

📦 What is this software?

⚠️ 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.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

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/OS

Implement 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\.'
