CVE-2017-17090 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:19.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream asterisk package and not the asterisk package as distributed by Ubuntu.
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.
