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.
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya one-X® Communicator | 5.2, 6.0 | Low | Upgrade to one-X® Communicator 6.1 or later |
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:
| Vulnerability | Mitigating Factors |
|---|---|
|
Buffer Overflow |
This is a Low because it would require direct user interaction within a local trusted domain. |
