Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-93mv-x874-956g. This link is maintained to preserve external references.

Original Description

The unsafe globals in Picklescan before 0.0.25 do not include ssl. Consequently, ssl.get_server_certificate can exfiltrate data via DNS after deserialization.
