Gentoo Linux Security Advisory

Title: sudo: Privilege Escalation (GLSA 201009-03)
Severity: high
Exploitable: local
Date: September 07, 2010
Bug(s): #322517, #335381
ID: 201009-03

Synopsis


The secure path feature and group handling in sudo allow local attackers to
escalate privileges.


Background


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


Affected Packages

Package: app-admin/sudo
Vulnerable: < 1.7.4_p3-r1
Unaffected: >= 1.7.4_p3-r1
Architectures: All supported architectures


Description


Multiple vulnerabilities have been reported in sudo:
  • Evan
    Broder and Anders Kaseorg of Ksplice, Inc. reported that the sudo
    'secure path' feature does not properly handle multiple PATH variables
    (CVE-2010-1646).
  • Markus Wuethrich of Swiss Post reported that
    sudo fails to restrict access when using Runas groups and the group
    (-g) command line option (CVE-2010-2956).


Impact


A local attacker could exploit these vulnerabilities to gain the
ability to run certain commands with the privileges of other users,
including root, depending on the configuration.


Workaround


There is no known workaround at this time.


Resolution


All sudo users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.4_p3-r1"
