Synopsis

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

Description

The version of python installed on the remote host is prior to 2.7.18-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2400 advisory.

 An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating optimisations were possible in the accumulator variable in hmac.compare_digest. (CVE-2022-48566)

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
