>Fix:

The patch at
  http://codelabs.ru/fbsd/ports/wireshark/1.8.2-fix-cve-2012-3548.diff
fixes the issue for me.  Here is the quality assurance page:
  http://codelabs.ru/fbsd/ports/qa/net/wireshark/1.8.2_1

When you'll be updating the port, please, include the line
{{{
Security: http://www.vuxml.org/freebsd/5415f1b3-f33d-11e1-8bd8-0022156e8794.html
}}}
into the commit log message.  The version specification inside
VuXML entry (security/vuxml/vuln.xml) should be changed from "1.9"
to the port version that will receive the fix for this CVE.
