Certainly not what we want from the people issuing client certificates. It sounds like this is a protocol level vulnerability affecting closed and Open Source vendors potentially, and it is public so posting it here. -- Kurt Seifried -- Red Hat -- Product Security -- Cloud PGP A90B F995 7350 148F 66BF 7554 160D 4553 5E26 7993 Red Hat Product Security contact: secalert@...hat.com
