The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200804-13
(Asterisk: Multiple vulnerabilities)
Asterisk upstream developers reported multiple vulnerabilities:
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).
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).
The SIP channel driver does
not correctly determine if authentication is required
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.
There is no known workaround at this time.
