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.

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
