Synopsis
========

Multiple remote vulnerabilities have been found in the LCDd server,
allowing execution of arbitrary code with the rights of the LCDd user.

Background
==========

LCDproc is a program that displays various bits of real-time system
information on an LCD. It makes use of a local server (LCDd) to collect
information to display on the LCD.

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

    -------------------------------------------------------------------
     Package           /    Vulnerable    /                  Unaffected
    -------------------------------------------------------------------
  1  app-misc/lcdproc       <= 0.4.4-r1                        >= 0.4.5

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

Due to insufficient checking of client-supplied data, the LCDd server
is susceptible to two buffer overflows and one string buffer
vulnerability. If the server is configured to listen on all network
interfaces (see the Bind parameter in LCDproc configuration), these
vulnerabilities can be triggered remotely.

Impact
======

These vulnerabilities allow an attacker to execute code with the rights
of the user running the LCDproc server. By default, this is the
"nobody" user.

Workaround
==========

A workaround is not currently known for this issue. All users are
advised to upgrade to the latest version of the affected package.

Resolution
==========

LCDproc users should upgrade to version 0.4.5 or later:

    # emerge sync

    # emerge -pv ">=app-misc/lcdproc-0.4.5"
    # emerge ">=app-misc/lcdproc-0.4.5"
