CVE-2013-6422

The GnuTLS backend in libcurl 7.21.4 through 7.33.0, when disabling digital signature verification CURLOPTSSLVERIFYPEER, also disables the CURLOPTSSLVERIFYHOST check for CN or SAN host name fields, which makes it easier for remote attackers to spoof servers and conduct man-in-the-middle MITM...

Ubuntu 12.04 LTS / 12.10 / 13.04 / 13.10 : curl vulnerability (USN-2058-1)

Marc Deslauriers discovered that libcurl incorrectly verified CN and SAN name fields when digital signature verification was disabled in the GnuTLS backend. When libcurl is being used in this uncommon way by specific applications, an attacker could exploit this to perform a man in the middle atta...
