I keep getting a notification when I access Tails that "this version of tails is known to have security issues? I updated to 1.4 last month and IIRC it was having this issue before the upgrade as well. This is in the notification applet that let's you know when TOR is ready after connecting to wifi. The security issue says something to do with the leaking of plaintext in clawsmail? Anyone else get this or know why/ how to fix it?
If you are not using Claws Mail or you are using Claws Mail with POP3 you are okay. The only fix is to not use Claws Mail with IMAP, but you will still see the message with every boot.
