Amazon Linux 2 : python3-tornado (ALAS-2025-2725)

high Nessus Plugin ID 213671

Synopsis

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

Description

The version of python3-tornado installed on the remote host is prior to 5.0.2-4. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2725 advisory.

Tornado is a Python web framework and asynchronous networking library. The algorithm used for parsing HTTP cookies in Tornado versions prior to 6.4.2 sometimes has quadratic complexity, leading to excessive CPU consumption when parsing maliciously-crafted cookie headers. This parsing occurs in the event loop thread and may block the processing of other requests. Version 6.4.2 fixes the issue. (CVE-2024-52804)

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

Run 'yum update python3-tornado' to update your system.
