Description

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. A vulnerability was found in curl. The issue occurs because curl wrongly allows HTTP cookies to be set for Top Level Domains (TLDs) if the hostname is provided with a trailing dot. This flaw allows arbitrary sites to set cookies that get sent to a different and unrelated site or domain by a malicious actor.
