picklescan before 0.0.29 fails to detect the built-in trace.Trace.run function when analyzing pickle files, allowing attackers to embed undetected malicious code. Remote attackers can craft malicious pickle files using trace.Trace.run in the reduce method to achieve arbitrary code execution when pickle.load processes the file.
