GLSA 200608-26: Wireshark: Multiple vulnerabilities

http://security.gentoo.org/

Severity:	normal
Title:	Wireshark: Multiple vulnerabilities
Date:	08/29/2006
Bugs:	#144946
ID:	200608-26

Synopsis

Wireshark is vulnerable to several security issues that may lead to a Denial of Service and/or the execution of arbitrary code.

Background

Wireshark is a feature-rich network protocol analyzer.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-analyzer/wireshark	< 0.99.3	>= 0.99.3	All supported architectures

Description

The following vulnerabilities have been discovered in Wireshark. Firstly, if the IPsec ESP parser is used it is susceptible to off-by-one errors, this parser is disabled by default; secondly, the SCSI dissector is vulnerable to an unspecified crash; and finally, the Q.2931 dissector of the SSCOP payload may use all the available memory if a port range is configured. By default, no port ranges are configured.

Impact

An attacker might be able to exploit these vulnerabilities, resulting in a crash or the execution of arbitrary code with the permissions of the user running Wireshark, possibly the root user.

Workaround

Disable the SCSI and Q.2931 dissectors with the "Analyse" and "Enabled protocols" menus. Make sure the ESP decryption is disabled, with the "Edit -> Preferences -> Protocols -> ESP" menu.

Resolution

All Wireshark users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-0.99.3"
