Synopsis: Moderate: dstat security update
Advisory ID: RHSA-2009:1619-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1619.html
Issue date: 2009-11-30
CVE Names: CVE-2009-3894
=====================================================================

1. Summary:

An updated dstat package that fixes one security issue is now available for
Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - noarch
Red Hat Enterprise Linux Desktop (v. 5 client) - noarch

3. Description:

Dstat is a versatile replacement for the vmstat, iostat, and netstat tools.
Dstat can be used for performance tuning tests, benchmarks, and
troubleshooting.

Robert Buchholz of the Gentoo Security Team reported a flaw in the Python
module search path used in dstat. If a local attacker could trick a
local user into running dstat from a directory containing a Python script
that is named like an importable module, they could execute arbitrary code
with the privileges of the user running dstat. (CVE-2009-3894)

All dstat users should upgrade to this updated package, which contains a
backported patch to correct this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
