Last Updated: 2013 May 29 16:47 UTC (GMT)
SummaryA vulnerability in the t-shell implementation of Cisco TelePresence System Software could allow an authenticated, remote attacker to exhaust the available memory and create a denial of service condition.
The vulnerability is due to improper handling of orphaned t-shell sessions. An attacker could exploit this vulnerability by opening several Secure Shell (SSH) sessions with the affected system. An exploit could allow the attacker to consume available memory. As a consequence, the affected system may become unreachable and unable to function properly. A hard reboot is needed to restore complete functionality.
