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.

Security readout for executives and security teams

This issue affects legacy KDE Konqueror certificate handling. If a user accepted a certificate based on the visible common name, Konqueror could treat hidden subjectAltName DNS names as accepted too. That could help spoof a website after a certificate warning is accepted. Exposure is most plausible on legacy desktops still using KDE Konqueror 3.5.5 or 3.95.00 for HTTPS browsing. Organizations without those versions are unlikely to be affected based on this bundle. Treat this as targeted legacy-browser risk, not an enterprise-wide emergency unless those old Konqueror versions remain in use. Priority should be inventory, retirement, and restriction from sensitive web workflows. Mitigation focus: Inventory systems for Konqueror 3.5.5 and 3.95.00 usage.; Check KDE or distribution guidance for fixed versions or supported replacements.; Restrict affected browsers from accessing sensitive HTTPS applications..
