Descriptions
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.

Si el controlador de canal chan_skinny (también conocido como protocolo SCCP) se inunda a base de determinadas peticiones, puede provocar que el proceso de asterisk utilice cantidades excesivas de memoria virtual, finalmente provocando que asterisk deje de procesar cualquier tipo de peticiones.
