Overview

Private keys for iTALC shipped on Live DVD


Packages

  • italc - Intelligent Teaching and Learning with Computers

Details

Stéphane Graber discovered that the iTALC private keys shipped with the
Edubuntu Live DVD were not correctly regenerated once Edubuntu was
installed. If an iTALC client was installed with the vulnerable keys, a
remote attacker could gain control of the system. Only systems using keys
from the Edubuntu Live DVD were affected.

Update instructions

After a standard system update, if you had originally installed from the Edubuntu Live DVD and the bad keys were found, you will need to redistribute the newly generated public keys to your iTALC clients and restart each session. For more details, see: https://wiki.ubuntu.com/iTalc/Keys
