  Severity: Low
     Title: ht://Dig: Cross-site scripting vulnerability
      Date: February 13, 2005
      Bugs: #80602
        ID: 200502-16

Synopsis
========

ht://Dig is vulnerable to cross-site scripting attacks.

Background
==========

ht://Dig is an HTTP/HTML indexing and searching system.

Affected packages
=================

    -------------------------------------------------------------------
     Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
  1 www-misc/htdig < 3.1.6-r7 >= 3.1.6-r7

Description
===========

Michael Krax discovered that ht://Dig fails to validate the 'config'
parameter before displaying an error message containing the parameter.
This flaw could allow an attacker to conduct cross-site scripting
attacks.

Impact
======

By sending a carefully crafted message, an attacker can inject and
execute script code in the victim's browser window. This allows to
modify the behaviour of ht://Dig, and/or leak session information such
as cookies to the attacker.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All ht://Dig users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-misc/htdig-3.1.6-r7"
