CVE-2026-40311 ImageMagick堆释放后重用漏洞

import os # Generate a test image with potentially malformed XMP data # This is a conceptual PoC. Actual exploitation requires specific byte patterns. # Create a minimal PNG file structure with a large XMP block data = b'\x89PNG\r\n\x1a\n' # ... (Skipping complex binary construction for brevity in thought process, will use python PIL approach if possible, or just a shell command suggestion) # Simulating a command line PoC # 1. Create a file with invalid XMP # 2. Run convert print("PoC: Create an image with invalid XMP profile and process it.") print("Step 1: Create malicious image (pseudo-code)") print("Step 2: magick identify malicious_image.png")
