Synopsis
========

A format string error in Vinagre may allow for the execution of
arbitrary code.

Background
==========

Vinagre is a VNC Client for the GNOME Desktop.

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

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  net-misc/vinagre       < 0.5.2                           >= 0.5.2

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

Alfredo Ortega (Core Security Technologies) reported a format string
error in the vinagre_utils_show_error() function in
src/vinagre-utils.c.

Impact
======

A remote attacker could entice a user into opening a specially crafted
.vnc file or connecting to a malicious server, possibly resulting in
the remote execution of arbitrary code with the privileges of the user
running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Vinagre users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/vinagre-0.5.2"
