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"

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