+ <background>
+ <p>
+ Asterisk is an open source telephony engine and tool kit.
+ </p>
+ </background>
+ <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 "&gt;=net-misc/asterisk-1.2.27"</code>
