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
-------------------------------------------------------------------
1 net-analyzer/wireshark < 0.99.3 >= 0.99.3
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"
