Asterisk Open Source 11.x before 11.12.1 and 12.x before 12.5.1 and Certified Asterisk 11.6 before 11.6-cert6, when using the res_fax_spandsp module, allows remote authenticated users to cause a denial of service (crash) via an out of call message, which is not properly handled in the ReceiveFax dialplan application.

CVE-2014-6610 Asterisk Open Source 11.x before 11.12.1 and 12.x before 12.5.1 and Certified Asterisk 11.6 before 11.6-cert6, when using the res_fax_spandsp module, allows remote authenticated users to cause a denial of service (crash) via an out of call message, which is not properly handled in the ReceiveFax dialplan application.

CVE-2014-4046 Asterisk Open Source 11.x before 11.10.1 and 12.x before 12.3.1 and Certified Asterisk 11.6 before 11.6-cert3 allows remote authenticated Manager users to execute arbitrary shell commands via a MixMonitor action.

CVE-2014-2286 main/http.c in Asterisk Open Source 1.8.x before 1.8.26.1, 11.8.x before 11.8.1, and 12.1.x before 12.1.1, and Certified Asterisk 1.8.x before 1.8.15-cert5 and 11.6 before 11.6-cert2, allows remote attackers to cause a denial of service (stack consumption) and possibly execute arbitrary code via an HTTP request with a large number of Cookie headers.

CVE-2014-8412 The (1) VoIP channel drivers, (2) DUNDi, and (3) Asterisk Manager Interface (AMI) in Asterisk Open Source 1.8.x before 1.8.32.1, 11.x before 11.14.1, 12.x before 12.7.1, and 13.x before 13.0.1 and Certified Asterisk 1.8.28 before 1.8.28-cert3 and 11.6 before 11.6-cert8 allows remote attackers to bypass the ACL restrictions via a packet with a source IP that does not share the address family as the first ACL entry.

CVE-2014-8418 The DB dialplan function in Asterisk Open Source 1.8.x before 1.8.32, 11.x before 11.1.4.1, 12.x before 12.7.1, and 13.x before 13.0.1 and Certified Asterisk 1.8 before 1.8.28-cert8 and 11.6 before 11.6-cert8 allows remote authenticated users to gain privileges via a call from an external protocol, as demonstrated by the AMI protocol.

CVE-2015-3008 Asterisk Open Source 1.8 before 1.8.32.3, 11.x before 11.17.1, 12.x before 12.8.2, and 13.x before 13.3.2 and Certified Asterisk 1.8.28 before 1.8.28-cert5, 11.6 before 11.6-cert11, and 13.1 before 13.1-cert2, when registering a SIP TLS device, does not properly handle a null byte in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.

The remote host is affected by the vulnerability described in GLSA-201411-10 (Asterisk: Multiple Vulnerabilities)

    Multiple unspecified vulnerabilities have been discovered in Asterisk.
      Please review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could exploit the vulnerabilities to cause a man in       the middle attack or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Multiple vulnerabilities has been discovered and corrected in asterisk :

Remote crash when handling out of call message in certain dialplan configurations (CVE-2014-6610).

Asterisk Susceptibility to POODLE Vulnerability (CVE-2014-3566).

Mixed IP address families in access control lists may permit unwanted traffic.

High call load may result in hung channels in ConfBridge.

Permission escalation through ConfBridge actions/dialplan functions.

The updated packages has been upgraded to the 11.14.1 version which is not vulnerable to these issues.

According to the version in its SIP banner, the version of Asterisk running on the remote host is potentially affected by a denial of service vulnerability in the ReceiveFax Dialplan application. This is due to a flaw in the 'res_fax_spandsp' module, which is caused by the improper handling of out-of-call messages. By using a specially crafted request, a remote attacker could exploit this to crash the application.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
