Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-4675-36f9-wf6r. This link is maintained to preserve external references.

Original Description

picklescan before 0.0.33 fails to block the ctypes module, allowing attackers to achieve remote code execution by invoking direct syscalls and accessing raw memory. Attackers can craft malicious pickle files using ctypes.WinDLL to load kernel32.dll and execute arbitrary commands, bypassing sandbox protections and gadget chain detection.
