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
===========
