http://security.gentoo.org/

Severity:	normal
Title:	Wireshark: Denial of Service
Date:	08/06/2008
Bugs:	#230411, #231587
ID:	200808-04

Synopsis

Multiple Denial of Service vulnerabilities have been discovered in Wireshark.

Background

Wireshark is a network protocol analyzer with a graphical front-end.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-analyzer/wireshark	< 1.0.2	>= 1.0.2	All supported architectures

Description

Multiple vulnerabilities related to memory management were discovered in the GSM SMS dissector (CVE-2008-3137), the PANA and KISMET dissectors (CVE-2008-3138), the RTMPT dissector (CVE-2008-3139), the syslog dissector (CVE-2008-3140) and the RMI dissector (CVE-2008-3141) and when reassembling fragmented packets (CVE-2008-3145).

Impact

A remote attacker could exploit these vulnerabilities by sending a specially crafted packet on a network being monitored by Wireshark or enticing a user to read a malformed packet trace file, causing a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All Wireshark users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-1.0.2"
