medium Tenable Self-Hosted Container Security Plugin ID 413390

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2021-21419)
