Descriptions

The uloc_acceptLanguageFromHTTP function in common/uloc.cpp in International Components for Unicode (ICU) through 57.1 for C/C++ does not ensure that there is a '\0' character at the end of a certain temporary array, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a call with a long httpAcceptLanguage argument.

La función uloc_acceptLanguageFromHTTP en common/uloc.cpp en International Components for Unicode (ICU) hasta la versión 57.1 para C/C++ no asegura que haya un carácter '\0' al final de un determinado array temporal, 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 con un argumento httpAcceptLanguage largo.
