Synopsis
The secure path feature and group handling in sudo allow local attackers to
escalate privileges.
2.
Impact Information
Background
sudo allows a system administrator to give users the ability to run
commands as other users.
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.

Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All sudo users should upgrade to the latest version:
Code Listing 3.1: Resolution |
