Severity: High
Title: sudo: Privilege escalation
Date: February 06, 2009
Bugs: #256633
ID: 200902-01
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
A vulnerability in sudo may allow for privilege escalation.
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 lt; 1.7.0 gt;= 1.7.0
Description
===========
Harald Koenig discovered that sudo incorrectly handles group
specifications in Runas_Alias (and related) entries when a group is
specified in the list (using %group syntax, to allow a user to run
commands as any member of that group) and the user is already a member
of that group.
Impact
======
A local attacker could possibly run commands as an arbitrary system
user (including root).
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All sudo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=app-admin/sudo-1.7.0"
References
==========
[ 1 ] CVE-2009-0034
