Background ========== Asterisk is an open source telephony engine and tool kit. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/asterisk < 1.2.27 >= 1.2.27 Description =========== 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. Resolution ========== All Asterisk users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.2.27" References ========== [ 1 ] CVE-2007-6170 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6170 [ 2 ] CVE-2007-6430 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6430 [ 3 ] CVE-2008-1332 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1332 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200804-13.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
