<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 ">=net-misc/asterisk-1.2.27"</code>
|
|
</resolution>
