Mboxrd and external MDA delivery.

<description>
<p>
David Watson discovered a vulnerability in getmail when it is
configured to run as root and deliver mail to the maildirs/mbox files
of untrusted local users. A malicious local user can then exploit a
race condition, or a similar symlink attack, and potentially cause
getmail to create or overwrite files in any directory on the system.
</p>
</description>
<impact type="high">
<p>
An untrusted local user could potentially create or overwrite files in
any directory on the system. This vulnerability may also be exploited
to have arbitrary commands executed as root.
</p>
</impact>
<workaround>
<p>
Do not run getmail as a privileged user; or, in version 4, use an
external MDA with explicitly configured user and group privileges.
</p>
</workaround>
<resolution>
<p>
All getmail users should upgrade to the latest version:
</p>
<code>
# emerge sync
# emerge -pv &quot;&gt;=net-mail/getmail-4.2.0&quot;
# emerge &quot;&gt;=net-mail/getmail-4.2.0&quot;</code>
</resolution>
