Details

YAMADA Yasuharu discovered that libcurl was vulnerable to a cookie
leak when doing requests across domains with matching tails. curl did
not properly restrict cookies to domains and subdomains. If a user or
automated system were tricked into processing a specially crafted URL,
an attacker could read cookie values stored by unrelated webservers.
