| Package | Affected versions | Patched versions |
|---|---|---|
| eventlet | ≥ 0.10, < 0.31.0≥ 0.10.0, < 0.31.0 | 0.31.0 |

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.
Version 0.31.0 restricts websocket frame to reasonable limits.
Restricting memory usage via OS limits would help against overall machine exhaustion. No workaround to protect Eventlet process.
