Hello,

The latest version of the python library apache-beam (2.29.0) has the following dependency: httplib2<0.18.0. Those versions of httplib2 have a severe vulnerability that you can see below.

The proposed fix is to upgrade the dependency to 0.19.0 or a more recent version.

Description:

httplib2 is a comprehensive HTTP client library for Python. In httplib2 before version 0.19.0, a malicious server which responds with long series of "\xa0" characters in the "www-authenticate" header may cause Denial of Service (CPU burn while parsing header) of the httplib2 client accessing said server. This is fixed in version 0.19.0 which contains a new implementation of auth headers parsing using the pyparsing library.

Thank you!
