Descriptions

The DecodeHSTSPreloadRaw function in net/http/transport_security_state.cc in Google Chrome before 43.0.2357.130 does not properly canonicalize DNS hostnames before making comparisons to HSTS or HPKP preload entries, which allows remote attackers to bypass intended access restrictions via a string that (1) ends in a . (dot) character or (2) is not entirely lowercase.

La función DecodeHSTSPreloadRaw en net/http/transport_security_state.cc en Google Chrome anterior a 43.0.2357.130 no canonicaliza correctamente los nombres de anfitriones DNS antes de hacer comparaciones con las entradas de precarga HSTS o HPKP, lo que permite a atacantes remotos evadir las restricciones de acceso a través de una cadena que (1) acaba en un caracter . (punto) o (2) no está completamente en minúsculas.
