Synopsis
========

Multiple vulnerabilities in the way sysstat handles symlinks may allow
an attacker to execute arbitrary code or overwrite arbitrary files

Background
==========

sysstat is a package containing a number of performance monitoring
utilities for Linux, including sar, mpstat, iostat and sa tools

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
app-admin/sysstat < 5.0.2 >= 5.0.2

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

There are two vulnerabilities in the way sysstat handles symlinks:

1. The isag utility, which displays sysstat data in a graphical
format, creates a temporary file in an insecure manner.

2. Two scripts in the sysstat package, post and trigger, create
temporary files in an insecure manner.

Impact
======

Both vulnerabilities may allow an attacker to overwrite arbitrary files
under the permissions of the user executing any of the affected
utilities.

Workaround
==========

A workaround is not currently known for this issue. All users are
advised to upgrade to the latest version of the affected package.

Resolution
==========

Systat users should upgrade to version 4.2 or later:

# emerge sync

# emerge -pv ">=app-admin/sysstat-5.0.2"
# emerge ">=app-admin/sysstat-5.0.2"
