The sudoers file is used to define the actions sudo users are
|
|
permitted to perform. Charles Morris discovered that a specific layout
|
|
of the sudoers file could cause the results of an internal check to be
|
|
clobbered, leaving sudo vulnerable to a race condition.

|
|
Successful exploitation would permit a local sudo user to execute
|
|
arbitrary commands as another user.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Reorder the sudoers file using the visudo utility to ensure the
|
|
'ALL' pseudo-command precedes other command definitions.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All sudo users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.6.8_p9"</code>
|
|
</resolution>
