Technical description

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.

Remediation

If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
