Severity:	normal
Title:	Wireshark: Multiple vulnerabilities
Date:	08/16/2007
Bugs:	#183520
ID:	200708-12

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	Architecture(s)
net-analyzer/wireshark	< 0.99.6	>= 0.99.6	All supported architectures

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"
