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"

References
