Title:
  CVE-2013-4545 - MitM attack/spoof

Status in “curl” package in Ubuntu:
  Fix Released

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.
