Vulnerability Assessment Summary
Ethereal: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200503-16
(Ethereal: Multiple vulnerabilities)


There are multiple vulnerabilities in versions of Ethereal earlier than
0.10.10, including:
The Etheric, 3GPP2 A11 and IAPP dissectors are vulnerable to buffer
overflows (CVE-2005-0704, CVE-2005-0699 and CVE-2005-0739).
The GPRS-LLC could crash when the "ignore cipher bit" option is
enabled (CVE-2005-0705).
Various vulnerabilities in JXTA and sFlow dissectors.

Impact

A possible hacker might be able to use these vulnerabilities to crash
Ethereal and execute arbitrary code with the permissions of the user
running Ethereal, which could be the root user.

Workaround

For a temporary workaround you can disable all affected protocol
dissectors. However, it is strongly recommended that you upgrade to the
latest stable version.
