(NTLM) authentication handling. By sending a specially crafted long

This could lead to execution of arbitrary attacker specified code with
the privileges of the application using the cURL library.

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
