Ubuntu Update for curl USN-2058-1

Please Install the Updated Packages.
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 attack to view sensitive information or alter encrypted communications.
