Ethereal/Wireshark is a network packet sniffing and packet analyzing utility.
The Ethereal project recently was renamed to Wireshark. Red Hat updated their packages in this RHSA to use Wireshark going forward on Red Hat Enterprise Linux 2.1, 3 and 4 and deprecate the Ethereal packages.
Ethereal/Wireshark was found to contain several potential Denial of Service (DoS) vulnerabilities when reading packets live from the network. The issues were centered around malformed packets in general as well as the dissectors for ANSI MAP, NCP NMAS, NDPStelnet, Checkpoint FW-1, MQ, XML NTP. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2006-3627, CVE-2006-3629, CVE-2006-3631, ( CVE-2006-3630, CVE-2006-3632, and CVE-2006-3628 to these issues.
In order for these vulnerabilities to be taken advantage of, an authenticated user on the local system would have to start Ethereal (tethereal). For Avaya system products, only Avaya Service technicians have permissions to run Wireshark (tshark).
More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya S87XX/S8500/S8300 | CM 1.x to CM 3.x | Low | See recommended actions below. This issue will be addressed in accordance with Avaya's Product Security Vulnerability Response Policy |
| Avaya CCS/SES | All | Low | See recommended actions below. This issue will be addressed in accordance with Avaya's Product Security Vulnerability Response Policy |
Recommended Actions:
For all system products which use
vulnerable
versions of Ethereal/Wireshark, 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 vendors guidance:
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya Interactive Response(IR) | All | None | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the IR application. The IR application does not require the software described in this advisory. |
| 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. |
Recommended Actions:
Avaya recommends that customers follow
recommended actions supplied by the Operating System vendor (e.g.
RedHat
Linux) or remove the affected package.
