Steve Holme discovered that libcurl incorrectly reused wrong connections when using protocols other than HTTP and FTP. This could lead to the use of unintended credentials, possibly exposing sensitive information. (CVE-2014-0138) Richard Moore discovered that libcurl incorrectly validated wildcard SSL certificates that contain literal IP addresses. An attacker could possibly exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2014-0139)
