Description Zack Miele 2023-02-23 15:39:21 UTC

An issue was discovered in the libsofia-sip fork in drachtio-server before 0.8.20. It allows remote attackers to cause a denial of service (daemon crash) via a crafted UDP message that leads to a failure of the libsofia-sip-ua/tport/tport.c self assertion.

Fix was pulled into the freeswitch/sofia-sip repository as well.
