Descriptions

libcurl wrongly allows cookies to be set for Top Level Domains (TLDs) if thehost name is provided with a trailing dot.curl can be told to receive and send cookies. curl's "cookie engine" can bebuilt with or without [Public Suffix List](https://publicsuffix.org/)awareness. If PSL support not provided, a more rudimentary check exists to atleast prevent cookies from being set on TLDs. This check was broken if thehost name in the URL uses a trailing dot.This can allow arbitrary sites to set cookies that then would get sent to adifferent and unrelated site or domain.

libcurl permite erróneamente que se establezcan cookies para Dominios de Alto Nivel (TLDs) si el nombre de host es proporcionado con un punto al final. curl puede recibir y enviar cookies. "cookie engine" de curl puede construirse con o sin conocimiento de la [Lista de Sufijos Públicos] (https://publicsuffix.org/). Si no es proporcionado soporte de PSL, se presenta una comprobación más rudimentaria para al menos evitar que sean establecidas cookies en los TLD. Esta comprobación no funcionaba si el nombre del host en la URL usaba un punto al final, lo que podía permitir que sitios arbitrarios establecieran cookies que sean enviadas a un sitio o dominio diferente y no relacionado
