Mandriva Linux Security Advisory 2014-187 – In cURL before 7.38.0, libcurl can be fooled to both sending cookies to wrong sites and into allowing arbitrary sites to set cookies for others. For this problem to trigger, the client application must use the numerical IP address in the URL to access the site. In cURL before 7.38.0, libcurl wrongly allows cookies to be set for Top Level Domains , thus making them apply broader than cookies are allowed. This can allow arbitrary sites to set cookies that then would get sent to a different and unrelated site or domain.
