Upgrade Ubuntu:16.04 python3.5 to version 3.5.2-2ubuntu0~16.04.13+esm14 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python3.5 package and not the python3.5 package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
There is a LOW severity vulnerability affecting CPython, specifically the 'http.cookies' standard library module.
When parsing cookies that contained backslashes for quoted characters in the cookie value, the parser would use an algorithm with quadratic complexity, resulting in excess CPU resources being used while parsing the value.
