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
