any server certificate validation when using HTTPS connections. If a
remote attacker were able to perform a man-in-the-middle attack, this
flaw could be exploited to alter or compromise confidential
information in applications that used the httplib2 library.

Note that Tenable Network Security has extracted the preceding
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."
