sudo: Privilege Escalation

sudo: Privilege Escalation The secure path feature and group handling in sudo allow local attackers to escalate privileges. sudo 2010-09-07 2010-09-07 322517 335381 local 1.7.4_p3-r1 1.7.4_p3-r1

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

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).

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"
