An issue was discovered in chan_skinny.c in Asterisk Open Source 13.18.2
and older, 14.7.2 and older, and 15.1.2 and older, and Certified Asterisk
13.13-cert7 and older. If the chan_skinny (aka SCCP protocol) channel
driver is flooded with certain requests, it can cause the asterisk process
to use excessive amounts of virtual memory, eventually causing asterisk to
stop processing requests of any kind.
