Bug Description

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-4545

From CVE report:
----------
cURL and libcurl 7.18.0 through 7.32.0, when built with OpenSSL, disables the certificate CN and SAN name field verification (CURLOPT_SSL_VERIFYHOST) when the digital signature verification (CURLOPT_SSL_VERIFYPEER) is disabled, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
----------

From developer: http://curl.haxx.se/docs/adv_20131115.html

Debian security advisory: http://www.debian.org/security/2013/dsa-2798

Patch (same fix as upstream and Debian) against 7.22.0-3ubuntu4.3 (current Precise) attached.
