Descriptions

In PHP 7.x before 7.0.21 and 7.1.x before 7.1.7, ext/intl/msgformat/msgformat_parse.c does not restrict the locale length, which allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) or possibly have unspecified other impact within International Components for Unicode (ICU) for C/C++ via a long first argument to the msgfmt_parse_message function.

En PHP, en versiones 7.x anteriores a la 7.0.21 y versiones 7.1.x anteriores a la 7.1.7, ext/intl/msgformat/msgformat_parse.c no restringe la longitud del valor locale, lo que permite que atacantes remotos provoquen una denegación de servicio (desbordamiento de búfer basado en pila y cierre inesperado de la aplicación) o, probablemente, causen otros impactos no especificados en International Components for Unicode (ICU) para C/C++ mediante un primer argumento largo a la función msgfmt_parse_message.
