Summary
Improper Handling of Highly Compressed Data (Data Amplification) and Memory Allocation with Excessive Size Value in eventlet
Details

Impact

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.

Patches

Version 0.31.0 restricts websocket frame to reasonable limits.

Workarounds

Restricting memory usage via OS limits would help against overall machine exhaustion. No workaround to protect Eventlet process.
