==========================================================Ubuntu Security Notice USN-1061-1         February 11, 2011
italc vulnerability
CVE-2011-0724
==========================================================
A security issue affects the following Edubuntu releases:

Edubuntu 9.10
Edubuntu 10.04 LTS
Edubuntu 10.10

This advisory does not apply to the corresponding versions of
Ubuntu, Kubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Edubuntu 9.10:
  italc-client                    1:1.0.9.1-0ubuntu16.1

Edubuntu 10.04 LTS:
  italc-client                    1:1.0.9.1-0ubuntu18.10.04.1

Edubuntu 10.10:
  italc-client                    1:1.0.9.1-0ubuntu18.10.10.1

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

Details follow:

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.
