Modification date: 21 Dec 2021
Type: security
Affected Mageia releases : 8
CVE: CVE-2021-42717

Description

Updated apache-mod_security packages fix security vulnerability:

ModSecurity mishandles excessively nested JSON objects. Crafted JSON
objects with nesting tens-of-thousands deep could result in the web
server being unable to service legitimate requests. Even a moderately
large (e.g., 300KB) HTTP request can occupy one of the limited NGINX
worker processes for minutes and consume almost all of the available
CPU on the machine (CVE-2021-42717).
