Descriptions

Mattermost version 7.0.x and earlier fails to sufficiently limit the in-memory sizes of concurrently uploaded JPEG images, which allows authenticated users to cause resource exhaustion on specific system configurations, resulting in server-side Denial of Service.

Mattermost versiones 7.0.x y anteriores, no limitan suficientemente los tamaños en memoria de las imágenes JPEG cargadas simultáneamente, lo que permite a usuarios autenticados causar el agotamiento de los recursos en configuraciones específicas del sistema, resultando en una Denegación de Servicio del lado del servidor
