How to fix?

Upgrade Ubuntu:18.04 python2.7 to version 2.7.15-4ubuntu4~18.04.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python2.7 package and not the python2.7 package as distributed by Ubuntu. See How to fix? for Ubuntu:18.04 relevant fixed versions and status.

urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a urllib.urlopen('local_file:///etc/passwd') call.
