I have been sent an alert from LL , about a exploit which could compromise security of ANY un-patched viewer, suffice to say the details will remain out of public view.
I am however pleased to announce that both me and the other kirsten viewer devs have been very busy people! Please find S21(7a) on the site, download at your earliest opportunity for best protection against this threat.
IF you do not find 7a available for your platform or you use any other viewer, I would suggest using the standard viewer 2 ( which should already be patched as of today ).
Best Wishes, KL
