"From Red Hat Security Advisory 2009:1619 :

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.

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."
