Arbitrary Code Execution in pdfminer.six via Crafted PDF Input

Summarypdfminer.six will execute arbitrary code from a malicious pickle file if provided with a malicious PDF file. The CMapDB.loaddata function in pdfminer.six uses pickle.loads to deserialize pickle files. These pickle files are supposed to be part of the pdfminer.six distribution stored in the...
