GLSA-200407-08 : Ethereal: Multiple security problems

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200407-08
(Ethereal: Multiple security problems)

There are multiple vulnerabilities in versions of Ethereal earlier than
0.10.5, including:
In some cases the iSNS dissector could cause Ethereal to
abort.
If there was no policy name for a handle for SMB SID snooping it
could cause a crash.
A malformed or missing community string could cause the SNMP
dissector to crash.

Impact :

An attacker could use these vulnerabilities to crash Ethereal 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. For SMB you can disable SID snooping in the SMB
protocol preference. However, it is strongly recommended to upgrade to
the latest stable version.

# emerge sync
# emerge -pv '>=net-analyzer/ethereal-0.10.5'
# emerge '>=net-analyzer/ethereal-0.10.5'
