Descriptions

The parser_yyerror function in the UTF-8 parser in Ruby 2.4.1 allows attackers to cause a denial of service (invalid write or read) or possibly have unspecified other impact via a crafted Ruby script, related to the parser_tokadd_utf8 function in parse.y. NOTE: this might have security relevance as a bypass of a $SAFE protection mechanism.

La función parser_yyerror en el analizador UTF-8 de Ruby versión 2.4.1, permite a los atacantes causar una denegación de servicio (lectura o escritura no válidas) o posiblemente tener otro impacto no especificado por medio de un script Ruby creado, relacionado con la función parser_tokadd_utf8 en parse.y. NOTA: esto podría tener relevancia para la seguridad como una omisión de un mecanismo de protección $SAFE.
