An ActiveX DLL library file installed by Avaya one-X® Communicator was found to contain a buffer overflow vulnerability. A user opening a malicious file or browsing to a malicious Web page on a trusted local domain Web server could cause the one-X® Communicator client to crash or allow arbitrary code to be executed.
Avaya would like to thank Parvez Anwar for responsibly reporting this issue.

Recommended Actions for System Products:
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 applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:
||This is a Low because it would require direct user interaction within a local trusted domain.|
