According to the version in its SIP banner, the version of Asterisk running on the remote host is potentially affected by the following vulnerabilities :

 - A stack-based buffer overflow error exists related to    SIP, HTTP and XMPP handling over TCP. Note that in the    case of 'Certified Asterisk', SIP is not affected.
   Further note that in the case of XMPP, an attacker must    establish an authenticated session first. (CVE-2012-5976)

 - An error exists related to device state cache and    anonymous calls that could allow system resources to be    exhausted. Note this vulnerability only affects systems    configured to allow anonymous calls. (CVE-2012-5977)

The remote host is affected by the vulnerability described in GLSA-201401-15 (Asterisk: Multiple vulnerabilities)

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

    A remote attacker could execute arbitrary code with the privileges of       the process, cause a Denial of Service condition, or obtain sensitive       information.
  Workaround :

    There is no known workaround at this time.

http://downloads.asterisk.org/pub/telephony/asterisk/ChangeLog-11.2.0 The Asterisk Development Team has announced a security release for Asterisk 11, Asterisk 11.1.2. This release addresses the security vulnerabilities reported in AST-2012-014 and AST-2012-015, and replaces the previous version of Asterisk 11 released for these security vulnerabilities. The prior release left open a vulnerability in res_xmpp that exists only in Asterisk 11; as such, other versions of Asterisk were resolved correctly by the previous releases.

This release is available for immediate download at http://downloads.asterisk.org/pub/telephony/asterisk/releases

The release of these versions resolve the following two issues :

  - Stack overflows that occur in some portions of Asterisk     that manage a TCP connection. In SIP, this is     exploitable via a remote unauthenticated session; in     XMPP and HTTP connections, this is exploitable via     remote authenticated sessions. The vulnerabilities in     SIP and HTTP were corrected in a prior release of     Asterisk; the vulnerability in XMPP is resolved in this     release.

  - A denial of service vulnerability through exploitation     of the device state cache. Anonymous calls had the     capability to create devices in Asterisk that would     never be disposed of. Handling the cachability of device     states aggregated via XMPP is handled in this release.

These issues and their resolutions are described in the security advisories.

For more information about the details of these vulnerabilities, please read security advisories AST-2012-014 and AST-2012-015.

Thank you for your continued support of Asterisk - and we apologize for having to do this twice!
