Attackers who persuade a user to install a crafted extension archive with many files can exhaust filesystem inodes, causing project writes and other processes to fail."

Los atacantes que persuaden a un usuario para instalar un archivo de extensión manipulado con muchos archivos pueden agotar los inodos del sistema de archivos, lo que provoca que las escrituras de proyectos y otros procesos fallen."
