Buffer overflow in DNS SRV and NAPTR lookups in Digium Asterisk 15.x before 15.6.2 and 16.x before 16.0.1 allows remote attackers 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.

CWE-119 Improper Restriction of Operations within the Bounds of a Memory Buffer

This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
