Description Lubomir Kundrak 2008-01-09 22:38:51 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2007-6591 to the following vulnerability:

KDE Konqueror 3.5.5 and 3.95.00, when a user accepts an SSL server certificate on the basis of the CN domain name in the DN field, regards the certificate as also accepted for all domain names in subjectAltName:dNSName fields, even though these fields cannot be examined in the product, which makes it easier for remote attackers to trick a user into accepting an invalid certificate for a spoofed web site.

The upstream bug report is here:

http://bugs.kde.org/show_bug.cgi?id=154921

By the sounds of things, this was fixed in 4.0.x; at least in 4.0.3 it seems to prevent this behaviour (either on purpose or by accident).  There doesn't seem to be any further details available.
