2. Avaya System Products using a Sun Microsystems Operating System:

Some Avaya system products are delivered with an Operating System from Sun Microsystems. Actions to be taken on these products are described below.

Product: Affected Version(s): Risk Level: Actions:
Avaya CMS R14/R14.1, R15 Low Upgrade to CMS R15ab.k or R15auxab.k or later
Avaya IR 3.0, 4.0 Low Use ipfilter (see ipfilter(5)) as detailed in the Sun advisory to block connections from the source IP addresses of the attacks.

Recommended Actions:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place; risk to Avaya's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update is available. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
