原文摘录

摘自原文(1734 字符中的一小部分)
Summary: libcurl fails to normalize the `hostname` and `cookie_domain` parameters passed to `psl_is_cookie_domain_acceptable` function. As a result a malicious site can set a super cookie if the victim requests the url with hostname with any upper case characters in the domain part of the hostname.
原文中的代码
Use helper function psl_str_to_utf8lower() for normalization of hostname and cookie_domain .
