NVD Description

Note: Versions mentioned in the description apply only to the upstream asterisk package and not the asterisk package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

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.
