Yes

Security database references:

More information:

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.
