picklescan - Zip Flag Bit Exploit Crashes Picklescan But Not PyTorch

picklescan before 0.0.23 fails to detect malicious pickle files inside PyTorch model archives when certain ZIP file flag bits are modified. By flipping specific bits in the ZIP file headers, an attacker can embed malicious pickle files that remain undetected by PickleScan while still being successfully loaded by PyTorch's torch.load(). This can lead to arbitrary code execution when loading a compromised model.

picklescan 数据伪造问题漏洞

picklescan是Matthieu Maitre个人开发者的一个安全扫描程序。 picklescan 0.0.23之前版本存在数据伪造问题漏洞，该漏洞源于无法检测ZIP文件头修改后的恶意pickle文件，可能导致任意代码执行。
