Ubuntu 9.10 / 10.04 LTS / 10.10 : italc vulnerability (USN-1061-1)

Description

Stephane 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.

Note that Tenable Network Security has extracted the preceding 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.
