<description>
|
||
<p>It was discovered that Gentoo’s default MUNGE installation suffered
|
||
from a privilege escalation vulnerability (munge user to root) due to
|
||
improper permissions and a runscript which called chown() on a user
|
||
controlled file.
|
||
</p>
|
||
</description>
|
||
<impact type="high">
|
||
<p>A local attacker, who either is already MUNGE’s system user or belongs
|
||
to MUNGE’s group, could potentially escalate privileges.
|
||
</p>
|
||
</impact>
|
||
<workaround>
|
||
<p>There is no known workaround at this time.</p>
|
||
</workaround>
|
||
<resolution>
|
||
<p>All MUNGE users should upgrade to the latest version:</p>
|
||
|
||
<code>
|
||
# emerge --sync
|
||
# emerge --ask --oneshot --verbose ">=sys-auth/munge-0.5.10-r2"
|

</code>
