<p>
CUPS provides a portable printing layer for UNIX-based operating
systems.

<description>
<p>
CUPS does not properly handle partially-negotiated SSL connections.
Upon receiving a partially-negotiated SSL connection, CUPS no longer
accepts further incoming connections, as the initial connection never
times out.
</p>
</description>
<impact type="normal">
<p>
An attacker could partially negotiate an SSL connection with a CUPS
server, and cause future connections to that server to fail, resulting
in a Denial of Service.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All CUPS users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-print/cups-1.2.9&quot;</code>
</resolution>
