| </p> |
| <ul> |
| <li>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).</li> |
| <li>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).</li> |
| </ul> |
| </description> |
| <impact type="high"> |
| <p> |

| ability to run certain commands with the privileges of other users, |
| including root, depending on the configuration. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |

| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.4_p3-r1"</code> |
