<resolution>
|

|
<p>All GRUB users should upgrade to the latest version:</p>
|
||
|
|
||
|
<code>
|
||
|
# emerge --sync
|
||
|
# emerge --ask --oneshot --verbose ">=sys-boot/grub-2.06-r3"
|
||
|
</code>
|
||
|
|
||
|
<p>After upgrading, make sure to run the grub-install command with options appropriate for your system. See the GRUB2 Gentoo Wiki page for directions. Your system will be vulnerable until this action is performed.</p>
