<p>
Asterisk is an open source telephony engine and tool kit.

<description>
<p>
Asterisk upstream developers reported multiple vulnerabilities:
</p>
<ul>
<li>The Call Detail Record Postgres logging engine (cdr_pgsql)
does not correctly escape the ANI and DNIS arguments before using them
in SQL statements (CVE-2007-6170).</li>
<li>When using database-based
registrations ("realtime") and host-based authentication, Asterisk does
not check the IP address when the username is correct and there is no
password provided (CVE-2007-6430).</li>
<li>The SIP channel driver does
not correctly determine if authentication is required
(CVE-2008-1332).</li>
</ul>
</description>
<impact type="normal">
<p>
Remote authenticated attackers could send specially crafted data to
Asterisk to execute arbitrary SQL commands and compromise the
administrative database. Remote unauthenticated attackers could bypass
authentication using a valid username to hijack other user's sessions,
and establish sessions on the SIP channel without authentication.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Asterisk users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/asterisk-1.2.27&quot;</code>
</resolution>
