Descriptions
The legacy Slack import feature in Mattermost version 6.7.0 and earlier fails to properly limit the sizes of imported files, which allows an authenticated attacker to crash the server by importing large files via the Slack import REST API.
La función de importación de Slack heredada en Mattermost versiones 6.7.0 y anteriores, no limita apropiadamente el tamaño de los archivos importados, lo que permite a un atacante autenticado bloquear el servidor importando archivos grandes por medio de la API REST de importación de Slack
