Synopsis
========

The webapp-config utility insecurely creates temporary files in a world
writable directory, potentially allowing the execution of arbitrary
commands.

Background
==========

webapp-config is a Gentoo Linux utility to help manage the installation
of web-based applications.

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

    -------------------------------------------------------------------
     Package                /  Vulnerable  /                Unaffected
    -------------------------------------------------------------------
  1  net-www/webapp-config       < 1.11                        >= 1.11

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

Eric Romang discovered webapp-config uses a predictable temporary
filename while processing certain options, resulting in a race
condition.

Impact
======

Successful exploitation of the race condition would allow an attacker
to disrupt the operation of webapp-config, or execute arbitrary shell
commands with the privileges of the user running webapp-config. A local
attacker could use a symlink attack to create or overwrite files with
the permissions of the user running webapp-config.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All webapp-config users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-www/webapp-config-1.11"

Availability
============

This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:

Concerns?
=========

Security is a primary focus of Gentoo Linux and ensuring the
confidentiality and security of our users machines is of utmost
importance to us. Any security concerns should be addressed to
security@...too.org or alternatively, you may file a bug at
