Description Jan Lieskovsky 2012-05-04 07:09:51 EDT
It was found that evolution-data-server, a back-end contacts, tasks and calendar information handling data server for Evolution, did not perform SSL certificates validation for secured connections. Evolution email client, using evolution-data-server's calendar caldav and addressbook webdav contact back-ends, holding the trust about the other side of the connection being the valid owner of the presented certificate, could be tricked into accepting a spoofed SSL certificate by mistake (MITM attack).
