  "summary": "Updated python-eventlet packages fix security vulnerability",
  "details": "Updated python-eventlet packages fix a security vulnerability:\n\nEventlet is a concurrent networking library for Python. A websocket\npeer may exhaust memory on Eventlet side by sending very large websocket\nframes. Malicious peer may exhaust memory on Eventlet side by sending\nhighly compressed data frame. A patch in version 0.31.0 restricts websocket\nframe to reasonable limits. As a workaround, restricting memory usage via\nOS limits would help against overall machine exhaustion, but there is no\nworkaround to protect Eventlet process (CVE-2021-21419).\n",
