In affected versions attackers that could provide arbitrary YAML input to an application that uses kaml could cause the application to endlessly loop while parsing the input. This could result in resource starvation and denial of service. This only affects applications that use polymorphic serialization with the default tagged polymorphism style. Applications using the property polymorphism style are not affected. YAML input for a polymorphic type that provided a tag but no value for the object would trigger the issue. Version 0.35.3 or later contain the fix for this issue."},{"lang":"es","value":"kaml es una implementación de código abierto del formato YAML con soporte para kotlinx.serialization. En las versiones afectadas, unos atacantes que pudieran proporcionar una entrada YAML arbitraria a una aplicación que usa kaml podría causar que la aplicación realice un bucle interminable mientras analiza la entrada. Esto podría resultar en una inanición de recursos y una denegación de servicio. Esto sólo afecta a las aplicaciones que usan una serialización polimórfica con el estilo de polimorfismo etiquetado predeterminado. Las aplicaciones que usan el estilo de polimorfismo de propiedades no están afectadas. La entrada de YAML para un tipo polimórfico que proporciona una etiqueta pero no un valor para el objeto desencadenaría el problema.
