NVD Description

Note: Versions mentioned in the description apply only to the upstream tkinter package and not the tkinter package as distributed by RHEL. See How to fix? for RHEL:7 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.
