GLSA-200407-08 : Ethereal: Multiple security problems

medium Nessus Plugin ID 14541

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.

Solution

All Ethereal users should upgrade to the latest stable version:
# emerge sync # emerge -pv '>=net-analyzer/ethereal-0.10.5' # emerge '>=net-analyzer/ethereal-0.10.5'
