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 3.8.15-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2PYTHON3.8-2023-007 advisory.2024-01-19: CVE-2022-48566 was added to this advisory.
A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int(text), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability. (CVE-2020-10735)
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 these issues but has instead relied only on the application's self-reported version number.
