The Asterisk Development Team would like to announce security releases for Asterisk 15 and 16. The available releases are released as versions 15.6.2 and
16.0.1.

These releases are available for immediate download at

https://downloads.asterisk.org/pub/telephony/asterisk/releases

The following security vulnerabilities were resolved in these versions:

There is a buffer overflow vulnerability in dns_srv and dns_naptr functions of
Asterisk that allows an attacker to crash Asterisk via a specially crafted DNS
SRV or NAPTR response. The attacker’s request causes Asterisk to segfault
and crash.
