Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of python38 installed on the remote host is prior to 3.8.5-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2PYTHON3.8-2023-008 advisory.- In Lib/tarfile.py in Python through 3.8.3, an attacker is able to craft a TAR archive leading to an infinite loop when opened by tarfile.open, because _proc_pax lacks header validation. (CVE-2019-20907)
- 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. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12;
v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.
(CVE-2020-14422)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
