   |       CVE Name       |                                                 |
   +------------------------------------------------------------------------+

   | Description | Input buffers were not properly escaped when providing   |
   |             | the ANI and DNIS strings to the Call Detail Record       |
   |             | Postgres logging engine. An attacker could potentially   |
   |             | compromise the administrative database containing users' |
   |             | usernames and passwords used for SIP authentication,     |
   |             | among other things.                                      |
   |             |                                                          |
   |             | This module is not active by default and must be         |
   |             | configured for use by the administrator. Default         |
   |             | installations of Asterisk are not affected.              |
   +------------------------------------------------------------------------+

   +------------------------------------------------------------------------+
   | Workaround | Convert your installation to use cdr_odbc with the        |
   |            | PgsqlODBC driver. This module provides similar            |
   |            | functionality but is not vulnerable.                      |
   +------------------------------------------------------------------------+

   +------------------------------------------------------------------------+
   |    Resolution    | Upgrade to Asterisk release 1.4.15 or higher.       |
   +------------------------------------------------------------------------+
