Descriptions

An issue was discovered in atftpd in atftp 0.7.1. It does not lock the thread_list_mutex mutex before assigning the current thread data structure. As a result, the daemon is vulnerable to a denial of service attack due to a NULL pointer dereference. If thread_data is NULL when assigned to current, and modified by another thread before a certain tftpd_list.c check, there is a crash when dereferencing current->next.

Fue encontrado un problema en atftpd en atftp versión 0.7.1. No bloquea el mutex thread_list_mutex anterior de asignar la estructura de datos del hilo actual. Como resultado, el dominio es vulnerable a un ataque de Denegación de Servicio (DoS) debido a una desreferencia de puntero NULL. Si thread_data es NULL cuando se asigna a actual, y se modifica por otro hilo anterior de una cierta comprobación del archivo tftpd_list.c, se produce un bloqueo al eliminar la referencia current->next.
