21 | <synopsis>Multiple vulnerabilities have been found in sudo which could result |
22 | in privilege escalation. |

35 | <background> |
36 | <p>sudo allows a system administrator to give users the ability to run |
37 | commands as other users. Access to commands may also be granted on a |
38 | range to hosts. |
39 | </p> |
40 | </background> |
41 | <description> |
42 | <p>Multiple vulnerabilities have been found in sudo:</p> |
43 | |
44 | <ul> |
45 | <li>sudo does not correctly validate the controlling terminal on a system |
46 | without /proc or when the tty_tickets option is enabled. |
47 | </li> |
48 | <li>sudo does not properly handle the clock when it is set to the epoch.</li> |
49 | </ul> |
50 | </description> |
51 | <impact type="high"> |
52 | <p>A local attacker with sudo privileges could connect to the stdin, |
53 | stdout, and stderr of the terminal of a user who has authenticated with |
54 | sudo, allowing the attacker to hijack the authorization of the other |
55 | user. Additionally, a local or physically proximate attacker could set |
56 | the system clock to the epoch, bypassing time restrictions on sudo |
57 | authentication. |
58 | </p> |
59 | </impact> |
60 | <workaround> |
61 | <p>There is no known workaround at this time.</p> |
62 | </workaround> |
63 | <resolution> |
64 | <p>All sudo users should upgrade to the latest version:</p> |
65 | |
66 | <code> |
67 | # emerge --sync |
68 | # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.6_p7" |
69 | </code> |
