Red Hat Security Advisory 2015-2159-06 - The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. It was found that the libcurl library did not correctly handle partial literal IP addresses when parsing received HTTP cookies. An attacker able to trick a user into connecting to a malicious server could use this flaw to set the user's cookie to a crafted domain, making other cookie-related issues easier to exploit. A flaw was found in the way the libcurl library performed the duplication of connection handles. If an application set the CURLOPT_COPYPOSTFIELDS option for a handle, using the handle's duplicate could cause the application to crash or disclose a portion of its memory.

Various other issues were also addressed.

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.

This could lead to the disclosure of cookies to the wrong site, and malicious sites being able to set cookies for others. Tim Ruehsen discovered that curl incorrectly allowed cookies to be set for Top Level Domains (TLDs). This could allow a malicious site to set a cookie that gets sent to other sites.
