Synopsis

The remote Red Hat host is missing a security update for python-jwcrypto.

Description

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2024:2559 advisory.

 - JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to version 1.5.6, an attacker can cause a denial of service attack by passing in a malicious JWE Token with a high compression ratio. When the server processes this token, it will consume a lot of memory and processing time. Version 1.5.6 fixes this vulnerability by limiting the maximum token length. (CVE-2024-28102)

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

Solution

Update the RHEL python-jwcrypto package based on the guidance in RHSA-2024:2559.
