[GLSA-200501-27] Ethereal: Multiple vulnerabilities

Vulnerability Assessment Summary
Ethereal: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200501-27
(Ethereal: Multiple vulnerabilities)

There are multiple vulnerabilities in versions of Ethereal earlier
than 0.10.9, including:
The COPS dissector could go into
an infinite loop (CVE-2005-0006).
The DLSw dissector could
cause an assertion, making Ethereal exit prematurely
(CVE-2005-0007).
The DNP dissector could cause memory
corruption (CVE-2005-0008).
The Gnutella dissector could cause
an assertion, making Ethereal exit prematurely (CVE-2005-0009).
The MMSE dissector could free statically-allocated memory
(CVE-2005-0010).
The X11 dissector is vulnerable to a string
buffer overflow (CVE-2005-0084).

Impact

A possible hacker might be able to use these vulnerabilities to crash
Ethereal, perform DoS by CPU and disk space utilization or even 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 by selecting Analyze->Enabled Protocols... and deselecting
them from the list. However, it is strongly recommended to upgrade to
the latest stable version.
