Descriptions

An incorrect handling of a special element in Busybox's ash applet leads to denial of service when processing a crafted shell command, due to the shell mistaking specific characters for reserved characters. This may be used for DoS under rare conditions of filtered command input.

Un manejo incorrecto de un elemento especial en el applet ash de Busybox conlleva una denegación de servicio cuando es procesado un comando shell diseñado, debido a que el shell confunde caracteres específicos con caracteres reservados. Esto puede ser usado para DoS bajo condiciones raras de entrada de comandos filtrados
