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 / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-admin/sudo < 1.7.4_p3-r1 >= 1.7.4_p3-r1
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:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.4_p3-r1"
