Buffer overflow in DNS SRV and NAPTR lookups in Digium Asterisk 15.x prior to 15.6.2 and 16.x prior to 16.0.1 allows remote malicious users to crash Asterisk via a specially crafted DNS SRV or NAPTR response, because a buffer size is supposed to match an expanded length but actually matches a compressed length.
