cmd5checkpw is a checkpassword compatible authentication program that
uses CRAM-MD5 authentication mode.
</p>
</background>
<description>
<p>
Florian Westphal discovered that cmd5checkpw is installed setuid
cmd5checkpw but does not drop privileges before calling execvp(), so
the invoked program retains the cmd5checkpw euid.
</p>
</description>
<impact type="low">
<p>
Local users that know at least one valid /etc/poppasswd user/password
combination can read the /etc/poppasswd file.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All cmd5checkpw users should upgrade to the latest available version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-mail/cmd5checkpw-0.22-r2&quot;</code>
</resolution>
