Title:	sandbox: Insecure temporary file handling
Date:	07/25/2005
Bugs:	#96782
ID:	200507-22

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	Architecture(s)
sys-apps/sandbox	< 1.2.11	>= 1.2.11	All supported architectures

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"
