Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

urllib in Python 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. (CVE-2019-9948)

Solution

Run 'yum update python' to update your system.
