Gentoo Linux Security Advisory

Title: webapp-config: Insecure temporary file handling (GLSA 200506-13)
Severity: normal
Exploitable: local
Date: June 17, 2005
Updated: December 30, 2007
Bug(s): #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: app-admin/webapp-config
Vulnerable: < 1.11
Unaffected: >= 1.11
Architectures: 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:
