Upgrade Debian:10 asterisk to version 1:13.18.1~dfsg-1 or higher.
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:10 relevant fixed versions and status.
An issue was discovered in Asterisk Open Source 13 before 13.18.1, 14 before 14.7.1, and 15 before 15.1.1 and Certified Asterisk 13.13 before 13.13-cert7. A memory leak occurs when an Asterisk pjsip session object is created and that call gets rejected before the session itself is fully established. When this happens the session object never gets destroyed. Eventually Asterisk can run out of memory and crash.
