<p>sudo (su “do”) allows a system administrator to delegate authority
|
||
|
|
to give certain users (or groups of users) the ability to run some (or
|
||
|
|
all) commands as root or another user while providing an audit trail of
|
||
|
|
the commands and their arguments.

<description>
|
||
|
|
<p>sudoedit in sudo is vulnerable to the escalation of privileges by local
|
||
|
|
users via a symlink attack. This can be exploited by a file whose full
|
||
|
|
path is defined using multiple wildcards in /etc/sudoers, as demonstrated
|
||
|
|
by “/home/<em>/</em>/file.txt.

<p>Local users are able to gain unauthorized privileges on the system.</p>

</impact>
|

|
<workaround>
|

<p>There is no known work around at this time.</p>

<resolution>
|
||
|
|
<p>All sudo users should upgrade to the latest version:</p>
