Synopsis
========

The sandbox utility may create temporary files in an insecure manner.

Background
==========

sandbox is a Gentoo Linux utility used by the Portage package
management system.

Affected packages
=================

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  sys-apps/sandbox      < 1.2.11                          >= 1.2.11

Description
===========

The Gentoo Linux Security Audit Team discovered that the sandbox
utility was vulnerable to multiple TOCTOU (Time of Check, Time of Use)
file creation race conditions.

Impact
======

Local users may be able to create or overwrite arbitrary files with the
permissions of the root user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All sandbox users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=sys-apps/sandbox-1.2.11"

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

This GLSA and any updates to it are available for viewing at
