| 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. |
