The Asterisk project reports :
PJProject has a limit on the number of TCP connections that it can
accept. Furthermore, PJProject does not close TCP connections it
accepts. By default, this value is approximately 60.
An attacker can deplete the number of allowed TCP connections by
opening TCP connections and sending no data to Asterisk.
If PJProject has been compiled in debug mode, then once the number of
allowed TCP connections has been depleted, the next attempted TCP
connection to Asterisk will crash due to an assertion in PJProject.
If PJProject has not been compiled in debug mode, then any further TCP
connection attempts will be rejected. This makes Asterisk unable to
process TCP SIP traffic.
Note that this only affects TCP/TLS, since UDP is connectionless.
