Amazon Linux AMI : python34, python36, python35 (ALAS-2020-1432)

high Nessus Plugin ID 140207

Language:

Synopsis

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

Description

The version of python34 installed on the remote host is prior to 3.4.10-1.52. The version of python35 installed on the remote host is prior to 3.5.9-1.28. The version of python36 installed on the remote host is prior to 3.6.12-1.19. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2020-1432 advisory.

 Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. (CVE-2020-14422)

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

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

Solution

Run 'yum update python34' to update your system.
 Run 'yum update python36' to update your system.
 Run 'yum update python35' to update your system.
