"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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
