Synopsis
========

Dillo is vulnerable to a format string bug, which may result in the
execution of arbitrary code.

Background
==========

Dillo is a small and fast multi-platform web browser based on GTK+.

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

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  www-client/dillo     < 0.8.3-r4                       >= 0.8.3-r4

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

Gentoo Linux developer Tavis Ormandy found a format string bug in
Dillo's handling of messages in a_Interface_msg().

Impact
======

An attacker could craft a malicious web page which, when accessed using
Dillo, would trigger the format string vulnerability and potentially
execute arbitrary code with the rights of the user running Dillo.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Dillo users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-client/dillo-0.8.3-r4"
