Updated python-eventlet packages fix security vulnerability

Publication date: 18 Jun 2021
Modification date: 18 Jun 2021
Type: security
Affected Mageia releases : 7 , 8
CVE: CVE-2021-21419

Description

Updated python-eventlet packages fix a security vulnerability:

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).
