Security Bulletin

Summary

An attacker could send a specially-crafted certificate to impersonate a 
server.

Vulnerability Details

CVEID: CVE-2014-0139

Description: cURL/libcURL could allow a remote attacker to bypass security 
restrictions, caused by an error in the hostmatch() function when validating 
certificates containing an IP address with a wildcard match within the Common
Name field. By sending a specially-crafted SSL certificate containing wildcard
characters, a remote attacker could exploit this vulnerability to spoof the 
server and launch further attacks on the system.
