Synopsis
========

Two vulnerabilities in sudo might allow local users to escalate
privileges and execute arbitrary code with root privileges.

Background
==========

sudo allows a system administrator to give users the ability to run
commands as other users.

Affected packages
=================

    -------------------------------------------------------------------
     Package         /  Vulnerable  /                       Unaffected
    -------------------------------------------------------------------
  1  app-admin/sudo     < 1.7.2_p4                         >= 1.7.2_p4

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

Multiple vulnerabilities have been discovered in sudo:

* Glenn Waller and neonsignal reported that sudo does not properly
  handle access control of the "sudoedit" pseudo-command
  (CVE-2010-0426).

* Harald Koenig reported that sudo does not properly set
  supplementary groups when using the "runas_default" option
  (CVE-2010-0427).

Impact
======

A local attacker with privileges to use "sudoedit" or the privilege to
execute commands with the "runas_default" setting enabled could
leverage these vulnerabilities to execute arbitrary code with elevated
privileges.

Workaround
==========

CVE-2010-0426: Revoke all "sudoedit" privileges, or use the full path
to sudoedit. CVE-2010-0427: Remove all occurrences of the
"runas_default" setting.

Resolution
==========

All sudo users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.2_p4"
