Wireshark is a network packet sniffing and packet analyzing utility.
The Ethereal project recently was renamed to Wireshark. Red Hat updated their packages to use Wireshark going forward on Red Hat Enterprise Linux 2.1, 3 and 4 and deprecated the Ethereal packages.
Wireshark was found to contain numerous Denial of Service (DoS) issues in the protocol dissectors for the LLT, IEEE 802.11, HTTP and TCP protocols when reading packets live from the network. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2007-0456, CVE-2007-0457, CVE-2007-0458 and CVE-2007-0459 to these issues.
In order for these vulnerabilities to be taken advantage of, an authenticated user on the local system would have to start Wireshark (tshark). 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 Communication Manager | CM 4.0.1 and earlier | Low | Upgrade to CM 5.0 or later. |
| Avaya EMMC | All | Low | This will not be addressed as no further releases are planned. |
| Avaya CCS/SES | SES 4.0 and earlier | Low | Upgrade to SES 5.0 or later. |
Recommended Actions:
For all system products which use
vulnerable
versions of 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 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 vendor's 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. |
