   |      CVE Name      |CVE-2007-4521                                      |
   +------------------------------------------------------------------------+

   +------------------------------------------------------------------------+
   | Description | If Asterisk is configured to use IMAP as its backend     |
   |             | storage for voicemail, then an e-mail sent to a user     |
   |             | with an invalid/corrupted MIME body will cause Asterisk  |
   |             | to crash when the user listens to their voicemail using  |
   |             | the phone.                                               |
   |             |                                                          |
   |             | This does not affect any other voicemail storage option, |
   |             | nor does it affect users who check their voicemail via   |
   |             | e-mail when using IMAP storage.                          |
   +------------------------------------------------------------------------+

   +------------------------------------------------------------------------+
   | Resolution | Since this is a minor issue, a new release is not         |
   |            | immediately planned. However, the issue will be fixed in  |
   |            | Asterisk Open Source version 1.4.12 when it is released.  |
