CVE-2014-4047 asterisk: DoS due to Exhaustion of Allowed Concurrent HTTP Connections (AST-2014-007)
Establishing a TCP or TLS connection to the configured HTTP
or HTTPS port respectively in http.conf and then not
sending or completing a HTTP request will tie up a HTTP
session. By doing this repeatedly until the maximum number
of open HTTP sessions is reached, legitimate requests are
blocked.
