Amazon Linux AMI : python27, python35, python36 (ALAS-2020-1342)

medium Nessus Plugin ID 133653

Language:

Synopsis

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

Description

The version of python27 installed on the remote host is prior to 2.7.16-1.131. The version of python35 installed on the remote host is prior to 3.5.7-1.25. The version of python36 installed on the remote host is prior to 3.6.10-1.16. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1342 advisory.

 The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server. (CVE-2019-16935)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update python27' to update your system.
 Run 'yum update python35' to update your system.
 Run 'yum update python36' to update your system.
