    Summary: python-httplib2 security update

    Details: httplib2 is a comprehensive HTTP client library, httplib2.py supports many features left out of other HTTP libraries. Security Fix(es): 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.(CVE-2021-21240)
