The regex crate features built-in mitigations to prevent denial of service attacks caused by untrusted regexes, or untrusted input matched by trusted regexes. Those (tunable) mitigations already provide sane defaults to prevent attacks. This guarantee is documented and it\u0027s considered part of the crate\u0027s API. Unfortunately a bug was discovered in the mitigations designed to prevent untrusted regexes to take an arbitrary amount of time during parsing, and it\u0027s possible to craft regexes that bypass such mitigations. This makes it possible to perform denial of service attacks by sending specially crafted regexes to services accepting user-controlled, untrusted regexes. All versions of the regex crate before or equal to 1.5.4 are affected by this issue. The fix is include starting from regex 1.5.5. All users accepting user-controlled regexes are recommended to upgrade immediately to the latest version of the regex crate. Unfortunately there is no fixed set of problematic regexes, as there are practically infinite regexes that could be crafted to exploit this vulnerability. Because of this, it us not recommend to deny known problematic regexes.\"},{\"lang\":\"es\",\"value\":\"regex es una implementaci\u00f3n de expresiones regulares para el lenguaje Rust. La caja de regex presenta mitigaciones incorporadas para prevenir ataques de denegaci\u00f3n de servicio causados por regexes no confiables, o por entradas no confiables coincidentes con regexes confiables. Estas mitigaciones (sintonizables) ya proporcionan valores predeterminados sanos para prevenir ataques. Esta garant\u00eda est\u00e1 documentada y se considera parte de la API de la caja. Desafortunadamente, se descubri\u00f3 un error en las mitigaciones dise\u00f1adas para evitar que las expresiones regulares no confiables tomen una cantidad arbitraria de tiempo durante el an\u00e1lisis, y es posible crear expresiones regulares que eludan dichas mitigaciones. Esto hace posible realizar ataques de denegaci\u00f3n de servicio enviando regexes especialmente dise\u00f1ados a servicios que aceptan regexes no confiables controlados por el usuario. Todas las versiones de regex crate anteriores o iguales a la 1.5.4 est\u00e1n afectadas por este problema. La correcci\u00f3n se incluye a partir de regex 1.5.5. Se recomienda a todos los usuarios que acepten regexes controlados por el usuario que actualicen inmediatamente a la \u00faltima versi\u00f3n del regex crate. Lamentablemente, no existe un conjunto fijo de regexes problem\u00e1ticos, ya que hay pr\u00e1cticamente infinitas regexes que podr\u00edan ser creadas para explotar esta vulnerabilidad.
