Description John Helmert III gentoo-dev Security 2021-06-23 23:39:09 UTC
CVE-2021-21419 (https://github.com/eventlet/eventlet/security/advisories/GHSA-9p9m-jm8w-94p2):

Eventlet is a concurrent networking library for Python. A websocket peer may exhaust memory on Eventlet side by sending very large websocket frames. Malicious peer may exhaust memory on Eventlet side by sending highly compressed data frame. A patch in version 0.31.0 restricts websocket frame to reasonable limits. As a workaround, restricting memory usage via OS limits would help against overall machine exhaustion, but there is no workaround to protect Eventlet process.


Fix in 0.31.0, we'll just depend on the stablereq here.
