This advisory from Red Hat deals specifically with versions of shadow-utils on Red Hat Enterprise Linux (RHEL) 3 and earlier. Some Avaya systems are affected by this advisory.
More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:
| Product: | Affected Version(s): | Risk Level: | Actions: |

For all system products which use vulnerable versions of
shadow-utils, Avaya recommends that customers restrict local
and network access to the server. This restriction should be
enforced through the use of physical security, firewalls, ACLs,
VPNs, and other generally-accepted networking practices until such
time as an update becomes available and can be installed.
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
