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. </p> </description> <impact type="normal"> <p> 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. </p> </impact> <workaround> <p> 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. </p> </workaround> <resolution> <p> All Wireshark users should upgrade to the latest version: </p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/wireshark-0.99.3"</code> </resolution> <references> <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4330">CVE-2006-4330</uri> <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4331">CVE-2006-4331</uri> <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4332">CVE-2006-4332</uri> <uri link="http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4333">CVE-2006-4333</uri> <uri link="http://www.wireshark.org/security/wnpa-sec-2006-02.html">Wireshark official advisory</uri> </references> <metadata tag="requester" timestamp="Fri, 25 Aug 2006 07:36:40 +0000"> jaervosz </metadata> <metadata tag="bugReady" timestamp="Sat, 26 Aug 2006 14:34:42 +0000"> falco </metadata> <metadata tag="submitter" timestamp="Sat, 26 Aug 2006 14:55:04 +0000"> falco </metadata> </glsa>
