Уязвимость некорректной установки cookies для доменов верхнего уровня (TLD) в libcurl
Описание
В библиотеке libcurl обнаружена уязвимость, которая позволяет некорректно устанавливать cookies для доменов верхнего уровня (TLD), если имя хоста указано с завершающей точкой. Это приводит к тому, что произвольные сайты могут устанавливать cookies, которые затем отправляются на другой, не связанный сайт или домен.
Затронутые версии ПО
Эта уязвимость затрагивает версии libcurl, в которых поддержка Public Suffix List не предусмотрена, а более примитивная проверка предотвращения установки cookies на TLD нарушена.

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.
