Gentoo Linux Security Advisory

Title: Wireshark: Multiple vulnerabilities (GLSA 200608-26)
Severity: normal
Exploitable: remote
Date: August 29, 2006
Bug(s): #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: net-analyzer/wireshark
Vulnerable: < 0.99.3
Unaffected: >= 0.99.3
Architectures: 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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-0.99.3"
