Updated asterisk packages fix CVE-2014-6610 and mitigate POODLE

Publication date: 26 Nov 2014
Type: security
Affected Mageia releases : 3 , 4
CVE: CVE-2014-6610


Updated asterisk packages fix security vulnerabilities:

In Asterisk Open Source 11.x before 11.12.1, when an out of call message,
delivered by either the SIP or PJSIP channel driver or the XMPP stack, is
handled in Asterisk, a crash can occur if the channel servicing the message
is sent into the ReceiveFax dialplan application while using the
res_fax_spandsp module (CVE-2014-6610).

In Asterisk Open Source 11.x before 11.13.1, the res_jabber and res_xmpp
module both use SSLv3 exclusively, and are hence susceptible to
CVE-2014-3566, a.k.a. POODLE. Also, the core TLS handling, used by the
chan_sip channel driver, Asterisk Manager Interface (AMI), and the Asterisk
HTTP server, defaults to allowing SSLv3/SSLv2 fallback. This allows a MITM
to potentially force a connection to fallback to SSLv3, exposing it to the
POODLE vulnerability.

Asterisk has been updated to version 11.14.1, which fixes the CVE-2014-6610
issue, and in which it no longer uses SSLv3 for the res_jabber/res_xmpp
modules. Additionally, when the encryption method is not specified, the
default handling in the TLS core no longer allows for a fallback to SSLv3
or SSLv2.  These changes mitigate the POODLE vulnerability.

Other security issues fixed in 11.14.1 include:

Mixed IP address families in access control lists may permit unwanted
traffic (AST-2014-012)

High call load may result in hung channels in ConfBridge (AST-2014-014).

Permission escalation through ConfBridge actions/dialplan functions

The DB dialplan function when executed from an external protocol (for
instance AMI), could result in a privilege escalation (AST-2014-018).
