Hi Steve, vendors, Richard Moore and Simon Ward reported flaws in the way: 1, Network Security Services (NSS) handled wildcard (*) character in the Common Name field of a x509v3 digital 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. References: [1] http://www.westpoint.ltd.uk/advisories/wp-10-0001.txt [2] http://bugs.gentoo.org/show_bug.cgi?id=335731 2, Qt software toolkit (QSslSocket) handled wildcard (*) character in the Common Name field of a x509v3 digital certificate. If an attacker is able to get a carefully-crafted certificate, signed by a Certificate Authority trusted by Konqueror / Arora web browsers, the attacker could use the certificate during the man-in-the-middle attack and potentially confuse Konqueror / Arora into accepting it by mistake. Different vulnerability than CVE-2009-2408. References: [3] http://www.westpoint.ltd.uk/advisories/wp-10-0001.txt [4] http://bugs.gentoo.org/show_bug.cgi?id=335730 Yet, in [1] Richard and Simon mention: "27 August 2010 At the time of writing the NSS (Firefox) and Qt repositories both contain fixes for this issue that will be included in their releases." so it is possible these two flaws already got their CVE identifiers. But if not, could you please allocate them? Thanks && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team
