RHSA-2009:1619 - Moderate: dstat security update

Synopsis

Moderate: dstat security update

Type/Severity

Security Advisory Moderate

Topic

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.

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.

Solution

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