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

+------------------------------------------------------------------------+
| Description | Input buffers were not properly escaped when providing |
| | lookup data to the Postgres Realtime 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 res_config_odbc with the |
| | PgsqlODBC driver. This module provides similar |
| | functionality but is not vulnerable. |
