KDE recently fixed an issue in the code checking host names of the server SSL certificates. Previously, it accepted certificate as valid for the site if it was issued for the user-specified host name, or if it was issued for an IP address to which user-specified host name resolved. An attacker able to get an SSL certificate form a trusted CA issued for an attacker-controlled IP address could perform a MITM attack, if they were also able to hijack victim's DNS to resolve host names to the attacker's IP. Fixed upstream in: https://projects.kde.org/projects/kde/kdelibs/repository/revisions/76f935197599a335a5fe09b78751ddb455248cf7 Patch is included in kdelibs 4.6.1. -- Tomas Hoger / Red Hat Security Response Team
