GLSA-200804-13 : Asterisk: Multiple vulnerabilities

This script is Copyright (C) 2008-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

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
(CVE-2008-1332).

Impact :

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.

Workaround :

There is no known workaround at this time.

Solution :

All Asterisk users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/asterisk-1.2.27'

Risk factor :

High / CVSS Base Score : 8.8
(CVSS2#AV:N/AC:M/Au:N/C:C/I:C/A:N)
