|Gentoo Linux Security Advisory
Title: sudo: Privilege Escalation (GLSA 201009-03)
Date: September 07, 2010
Bug(s): #322517, #335381
The secure path feature and group handling in sudo allow local attackers to
sudo allows a system administrator to give users the ability to run
commands as other users.
Vulnerable: < 1.7.4_p3-r1
Unaffected: >= 1.7.4_p3-r1
Architectures: All supported architectures
Multiple vulnerabilities have been reported in sudo:
Broder and Anders Kaseorg of Ksplice, Inc. reported that the sudo
'secure path' feature does not properly handle multiple PATH variables
- 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).
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.
There is no known workaround at this time.
All sudo users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.4_p3-r1"
