Description Jan Lieskovsky 2010-09-03 15:53:02 UTC
Richard Moore and Simon Ward reported flaw in the way Qt software toolkit
handled wildcard characters 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.
