Description

<em style='font-weight:bold;'>(Description Provided by <a href="http://cve.mitre.org/cgi-bin/cvename.cgi?name=2009-2408" target="_blank">CVE</a>)</em> : Mozilla Network Security Services (NSS) before 3.12.3, Firefox before 3.0.13, Thunderbird before 2.0.0.23, and SeaMonkey before 1.1.18 do not properly handle a '\0' 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. NOTE: this was originally reported for Firefox before 3.5.

I track security updates for the following vendors: Apple, Cisco, FreeBSD, Microsoft, Red Hat, and Sun Microsystems. I chose these vendors based on my own needs for the networks and systems I manage. I’ve also found that updates from these vendors tend to catch the major updates necessary for common software applications. If you have other vendors you would like me to provide updates for, send me a message . Red Hat, Inc.
