Description Jan Lieskovsky 2010-09-03 15:27:36 UTC

Richard Moore and Simon Ward reported flaws in the way browsers such
as Firefox handled wildcard characters in the Common Name field of
a certificate. If an attacker is able to get a carefully-crafted certificate,
signed by a Certificate Authority trusted by Firefox, the attacker could
use the certificate during the man-in-the-middle attack and potentially
confuse Firefox into accepting it by mistake. Different vulnerability than
CVE-2009-2408.
