 Summary
 
 A vulnerability in Cisco Meeting Server versions prior to 2.2.2 could
allow an authenticated, remote attacker to cause the system to reload,
resulting in a denial of service (DoS) condition.
The vulnerability is due to video calls being made on systems with a
particular configuration. An attacker could exploit this by knowing a
valid URI that directs to a Cisco Meeting Server. An attacker could
then make a video call and cause the system to reload.
There are no workarounds that address this vulnerability.
