GLSA 200506-13: webapp-config: Insecure temporary file handling

http://security.gentoo.org/

Severity:	normal
Title:	webapp-config: Insecure temporary file handling
Date:	06/17/2005
Bugs:	#91785
ID:	200506-13

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	Architecture(s)
app-admin/webapp-config	< 1.11	>= 1.11	All supported architectures

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 ">=app-admin/webapp-config-1.11"
