CVE Name CVE-2014-2286<br>
<br>
Description Sending a HTTP request that is handled by Asterisk with a<br>
large number of Cookie headers could overflow the stack.<br>
You could even exhaust memory if you sent an unlimited<br>
number of headers in the request.<br>
<br>
Resolution The patched versions now handle headers in a fashion that<br>
prevents a stack overflow. Users should upgrade to a<br>
corrected version, apply the released patches, or disable<br>
HTTP support.<br>
