| <background> |
| <p> |
| sudo allows a system administrator to give users the ability to run |
| commands as other users. |
| </p> |
| </background> |
| <description> |
| <p> |
| Harald Koenig discovered that sudo incorrectly handles group |
| specifications in Runas_Alias (and related) entries when a group is |
| specified in the list (using %group syntax, to allow a user to run |
| commands as any member of that group) and the user is already a member |
| of that group. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| A local attacker could possibly run commands as an arbitrary system |
| user (including root). |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All sudo users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.7.0"</code> |
| </resolution> |
