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 lt; 1.11 gt;= 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 "gt;=net-www/webapp-config-1.11"

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

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

========

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@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
