CVE-2012-6086 zabbix: Improper use of cURL API might lead to improper SSL certificate verification (MiTM)
A security flaw was found in the way Zabbix, an open-source monitoring solution for IT infrastructure, used (lib)cURL's CURLOPT_SSL_VERIFYHOST variable, when doing certificate validation (value of '1' meaning only check for the existence of a common name was used instead of value '2' - which also checks if the particular common name matches the requested hostname of the server). A rogue service could use this flaw to conduct man-in-the-middle (MiTM) attacks.
