Amazon Linux AMI : python27, python34, python35 (ALAS-2020-1454)

high Nessus Plugin ID 142975

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 2.7.18-2.140. The version of python34 installed on the remote host is prior to 3.4.10-1.53. The version of python35 installed on the remote host is prior to 3.5.10-1.29. It is, therefore, affected by a vulnerability as referenced in the ALAS-2020-1454 advisory.

 http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request. (CVE-2020-26116)

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 python34' to update your system.
 Run 'yum update python35' to update your system.
