GLSA-200804-13 : Asterisk: Multiple vulnerabilities
high Nessus Plugin ID 31960
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'
