Yamada Yasuharu discovered that cURL, an URL transfer library, is vulnerable to expose potentially sensitive information when doing requests across domains with matching tails. Due to a bug in the tailmatch function when matching domain names, it was possible that cookies set for a domain ample.com could accidentally also be sent by libcurl when communicating with example.com . Both curl the command line tool and applications using the libcurl library are vulnerable.

For the stable distribution (squeeze), this problem has been fixed in version 7.21.0-2.1+squeeze3. For the testing distribution (wheezy), this problem has been fixed in version 7.26.0-1+wheezy2. For the unstable distribution (sid), this problem has been fixed in version 7.29.0-2.1. We recommend that you upgrade your curl packages.

curl is a client to get files from servers using any of the supported protocols. The command is designed to work without user interaction or any kind of interactivity.
