USN-2167-1: curl vulnerabilities

Packages

curl - HTTP, HTTPS, and FTP client and client libraries

Details

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 machine-in-the-middle attack to view sensitive
information or alter encrypted communications. (CVE-2014-0139)
