Descriptions

In ncurses, possibly a 6.x version, there is a NULL pointer dereference at the function _nc_name_match that will lead to a denial of service attack. NOTE: the original report stated version 6.1, but the issue did not reproduce for that version according to the maintainer or a reliable third-party

** EN DISPUTA ** En ncurses 6.1, hay una desreferencia de puntero NULL en la función _nc_name_match que conducirá a un ataque de denegación de servicio (DoS). NOTA: el informe original indicaba la versión 6.1, pero el problema no se reprodujo para esa versión según mantenedor o un tercero fiable.
