Synopsis
========
There is a format string flaw in Pound, allowing remote execution of
arbitrary code with the rights of the Pound process.
Background
==========
Pound is a reverse proxy, load balancer and HTTPS front-end. It allows
to distribute the load on several web servers and offers a SSL wrapper
for web servers that do not support SSL directly.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected

1 net-www/pound <= 1.5 >= 1.6
Description
===========
A format string flaw in the processing of syslog messages was
discovered and corrected in Pound.
Impact
======
This flaw may allow remote execution of arbitrary code with the rights
of the Pound daemon process. By default, Gentoo uses the "nobody" user
to run the Pound daemon.
Workaround
==========
There is no known workaround at this time. All users are advised to
upgrade to the latest available version of Pound.
Resolution
==========
All users of Pound should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=net-www/pound-1.6"
# emerge ">=net-www/pound-1.6"
