How to fix?

Upgrade Ubuntu:16.04 python3.5 to version 3.5.2-2ubuntu0~16.04.1 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.

Integer overflow in the get_data function in zipimport.c in CPython (aka Python) before 2.7.12, 3.x before 3.4.5, and 3.5.x before 3.5.2 allows remote attackers to have unspecified impact via a negative data size value, which triggers a heap-based buffer overflow.
