Descriptions

The get_icu_value_internal function in ext/intl/locale/locale_methods.c in PHP before 5.5.36, 5.6.x before 5.6.22, and 7.x before 7.0.7 does not ensure the presence of a '\0' character, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted locale_get_primary_language call.

La función get_icu_value_internal en ext/intl/locale/locale_methods.c en PHP en versiones anteriores a 5.5.36, 5.6.x en versiones anteriores a 5.6.22 y 7.x en versiones anteriores a 7.0.7 no asegura la presencia de un carácter '\0', lo que permite a atacantes remotos provocar una denegación de servicio (lectura fuera de rango) o posiblemente tener otro impacto no especificado a través de una llamada locale_get_primary_language manipulada.
