Re: TS-2007-001-0: BlueCat Networks Adonis Linux-HA heartbeat DoS Vulnerability

[bmiskov () bluecatnetworks com]

In response to this security advisory, BlueCat would like to post the following:

BlueCat acknowledges the existence of this issue and our testing indicates that a temporary outage may result from this 
Denial of Service attack.  System monitoring tools will alert the Adonis administrator of this issue immediately so 
that normal service can be reestablished with minimal impact.  We have confirmed that there is no persistent damage to 
the system as a result of this attack and the attack will not compromise any settings or information on the Adonis 
systems.

BlueCat is taking the following steps to address this issue:
1. Release a patch that will modify the firewall rules to restrict all traffic on port 694 to the cluster partner. The 
patch should be available later today - Friday, August 3rd. 

2. Update the version of the Heartbeat software to address this issue permanently.  This patch will be made available 
later this month.

To reduce the risk of this DoS attack, BlueCat recommends that customers check their firewall/router settings to ensure 
that UDP port 694 is closed. Since HA cluster partners must operate on the same subnet, there is no reason that any 
traffic on this port is required except between the cluster partners themselves.

For any BlueCat customer that wishes to obtain the patch, or seek more information on the matter, please feel free to 
contact BlueCat Network's Customer Care at 1.866.491.2228.
