OpenSSH is an implementation of an SSH server and SSH/SCP/SFTP clients.
OpenSSH was found to contain a flaw in the way Kerberos authenticated logins were handled by GSSAPI. A user could potentially take advantage to authenticate with OpenSSH's SSH daemon via a method other than GSSAPI and still be given GSSAPI credentials. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2798 to this issue.
More information about this vulnerability can be found in the security advisory issued by RedHat Linux:
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya Messaging Storage Server | MSS 3.0, 3.1 | Low | Upgrade to MSS 4.0 or later. |
Recommended Actions:
For all system products which use
vulnerable
versions of openssh, 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 the upgrade 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 vendors guidance.
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| CVLAN | All | None | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the CVLAN application. The CVLAN application does not require the software described in this advisory. |
| Avaya Integrated Management Suite(IMS) | All | None | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the IMS application. The IMS application does not require the software described in this advisory. |
