Synopsis
========

A vulnerability in Lsyncd allows execution of arbitrary code.

Background
==========

A daemon to synchronize local directories using rsync.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-admin/lsyncd             < 2.1.6                    >= 2.1.6

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

default-rsyncssh.lua in Lsyncd performed insufficient sanitising of
filenames.

Impact
======

An attacker, able to control files processed by Lsyncd, could possibly
execute arbitrary code with the privileges of the process or cause a
Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Lsyncd users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-admin/lsyncd-2.1.6"
