CVE-2021-27025

Se ha detectado un fallo en Puppet Agent donde el agente puede ignorar silenciosamente la configuración de Augeas o puede ser vulnerable a una condición de denegación de servicio antes del primer "pluginsync".

A configuration flaw was found in Puppet Agent where the agent silently ignores Augeas settings. This flaw allows a network attacker to cause a denial of service before the first pluginsync. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Puppet lets you centrally manage every important aspect of your system using a cross-platform specification language that manages all the separate elements normally aggregated in different files, like users, cron jobs, and hosts, along with obviously discrete elements like packages, services, and files. Provides the central puppet server daemon which provides manifests to clients. The server can also function as a certificate authority and file server. This puppet headless subpackage may be used when there is no need to have puppet agent running as a service, for example, in a container image.
