Summary

python-twisted security update

Details

Twisted is an event-based framework for internet applications, supporting Python 2.7 and Python 3.5+. It includes modules for many different purposes, including the following:

Security Fix(es):

A denial of service vulnerability exists in Twisted framework when handling DNS compression pointer chains. A single malformed TCP packet is sufficient to block the Twisted reactor's event loop for several seconds. Because Twisted operates on a single-threaded cooperative multitasking model, this results in a common Denial of Service (DoS) attack. During this process, the server becomes unable to handle new connections, process I/O, or respond to existing requests, effectively paralyzing the server for the duration of decompression.(CVE-2026-42304)
