USN-1948-1: httplib2 vulnerability

Publication date

9 September 2013

Overview

Fraudulent security certificates could allow sensitive information to be exposed when accessing the Internet.


Packages

Details

It was discovered that httplib2 only validated SSL certificates on the
first request to a connection, and didn't report validation failures on
subsequent requests. If a remote attacker were able to perform a
machine-in-the-middle attack, this flaw could possibly be exploited in certain
scenarios to alter or compromise confidential information in applications
that used the httplib2 library.
