Synopsis
========
Multiple vulnerabilities have been discovered in Wireshark, allowing
for the remote execution of arbitrary code and a Denial of Service.
Background
==========
Wireshark is a network protocol analyzer with a graphical front-end.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/wireshark < 0.99.6 >= 0.99.6
Description
===========
Wireshark doesn't properly handle chunked encoding in HTTP responses
(CVE-2007-3389), iSeries capture files (CVE-2007-3390), certain types
of DCP ETSI packets (CVE-2007-3391), and SSL or MMS packets
(CVE-2007-3392). An off-by-one error has been discovered in the
DHCP/BOOTP dissector when handling DHCP-over-DOCSIS packets
(CVE-2007-3393).
Impact
======
A remote attacker could send specially crafted packets on a network
being monitored with Wireshark, possibly resulting in the execution of
arbitrary code with the privileges of the user running Wireshark which
might be the root user, or a Denial of Service.
Workaround
==========
In order to prevent root compromise, take network captures with tcpdump
and analyze them running Wireshark as a least privileged user.
Resolution
==========
All Wireshark users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-0.99.6"
