Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258

Summary

cURL provides the libcurl library and a command line tool for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.
A flaw was found in the way libcurl matched domains associated with cookies. This could lead to cURL or an application linked against libcurl sending the wrong cookie if only part of the domain name matched the domain associated with the cookie, disclosing the cookie to unrelated hosts. (CVE-2013-1944)
Red Hat would like to thank the cURL project for reporting this issue. Upstream acknowledges YAMADA Yasuharu as the original reporter.
Users of curl should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using libcurl must be restarted for the update to take effect.
