Red Hat Product Errata RHSA-2010:0475 - Security Advisory
Issued:
2010-06-15
Updated:
2010-06-15

RHSA-2010:0475 - Security Advisory

  • Overview
  • Updated Packages

Synopsis

Moderate: sudo security update

Type/Severity

Security Advisory: Moderate

Topic

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

The Red Hat Security Response Team has rated this update as having moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

Description

The sudo (superuser do) utility allows system administrators to give
certain users the ability to run commands as root.

A flaw was found in the way sudo handled the presence of duplicated
environment variables. A local user authorized to run commands using sudo
could use this flaw to set additional values for the environment variables
set by sudo, which could result in those values being used by the executed
command instead of the values set by sudo. This could possibly lead to
certain intended restrictions being bypassed, such as the secure_path
setting. (CVE-2010-1646)

Red Hat would like to thank Anders Kaseorg and Evan Broder of Ksplice, Inc.
for responsibly reporting this issue.

Users of sudo should upgrade to this updated package, which contains a
backported patch to correct this issue.

Solution

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
