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 R13/R13.1, R14/R14.1, R15 Low Customers on CMS version R13 must first upgrade to R13.1 then apply patch 114014-22 to resolve this issue.
Customers on CMS version R14 must first upgrade to R14.1 then apply patch 114014-22 to resolve this issue.
Customers on CMS version R15, apply patch 125731-04 to resolve this issue.
Avaya IR 3.0, 4.0 Low IR does not use or support the affected libxml2 library routines. Therefore Avaya will not verify the patch for use with IR

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.
