Last modified
CVE-2018-19278 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.58% chance of exploitation in the next 30 days.
