CVE-2009-3044

Opera < 10.00 - SSL Server Spoofing via Null or Invalid Wildcard in Certificate CN

Title source: llm

Description

Opera before 10.00 does not properly handle a (1) '\0' character or (2) invalid wildcard character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.
