CVE-2018-10851
PowerDNS Authoritative Server 3.3.0 up to 4.1.4 excluding 4.1.5 and 4.0.6, and PowerDNS Recursor 3.2 up to 4.1.4 excluding 4.1.5 and 4.0.9, are vulnerable to a memory leak while parsing malformed records that can lead to remote denial of service.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.04%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
