Eclipse OMR, NULL Pointer Dereference, CVE-2025-1470 (Medium)

How the Mentioned CVE Works:

CVE-2025-1470 is a vulnerability in Eclipse OMR, affecting versions from the initial contribution up to 0.4.0. The issue arises in the internal port library and utilities for z/OS systems, specifically in the `atoe` functions. These functions fail to check for NULL return values or memory allocation failures, leading to potential NULL pointer dereferences. This can cause application crashes or undefined behavior. Starting from version 0.5.0, the issue has been addressed by implementing proper checks for NULL return values and memory allocation failures.

What Undercode Say:

Analytics:

• CVSS Score: 5.1 (Medium)
• Vector: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N
• Affected Systems: z/OS platforms using Eclipse OMR versions ≤ 0.4.0.
• Exploitability: Low, as it requires specific conditions to trigger a crash.

Commands:

1. Check Eclipse OMR Version:

omrversion --check

2. Upgrade to Fixed Version:

sudo apt-get update && sudo apt-get install eclipse-omr=0.5.0

Exploit Details:

• Trigger: Call `atoe` functions with memory allocation failures or NULL pointers.
• Impact: Application crash due to NULL pointer dereference.

Protection Measures:

1. Upgrade: Update to Eclipse OMR version 0.5.0 or later.
2. Code Review: Audit usage of `atoe` functions in custom code.
3. Input Validation: Ensure proper error handling for memory allocation.

Code Snippets:

• Vulnerable Code:

  char result = atoe(input);
  // No NULL check before using result
  

• Fixed Code:

  char result = atoe(input);
  if (result == NULL) {
  // Handle error
  }

Tools:

• Static Analysis: Use tools like Coverity or SonarQube to detect NULL pointer issues.
• Debugging: GDB or Valgrind to trace crashes.

Mitigation Steps:

1. Apply patches provided by Eclipse Foundation.

1. Monitor system logs for crashes related to `atoe` functions.

3. Implement fail-safe mechanisms in critical systems.
