Descriptions

Twisted is an event-based framework for internet applications, supporting Python 3.6+. The HTTP 1.0 and 1.1 server provided by twisted.web could process pipelined HTTP requests out-of-order, possibly resulting in information disclosure. This vulnerability is fixed in 24.7.0rc1.

USN-6988-1 fixedCVE-2024-41671 in Twisted. The USN incorrectly stated that previous releases were unaffected. This update provides the equivalent fix for Ubuntu 22.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 18.04 LTS. Ben Kallus discovered that Twisted incorrectly handled response order when processing multiple HTTP requests. A remote attacker could possibly use this issue to delay and manipulate responses. This issue only affected Ubuntu 24.04 LTS.
