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 deprecate the Ethereal packages.
A number of flaws were reported in the HTTP, WBXML, LDAP and XOT protocol dissectors in Wireshark. If Wireshark were to capture a malformed packet from the network, it could cause Wireshark to crash or stop responding. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2006-4805, CVE-2006-5468, CVE-2006-5469, and CVE-2006-5740 to these issues.
A single NULL byte heap buffer overflow was reported in the MIME Multipart dissector in Wireshark. When reading a malformed MIME Multipart packet, Wireshark could crash or possibly execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-4574 to this issue.
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: |

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: |
|---|---|---|---|
| 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. |
