CVE-REV: default

CVE-ID: CVE-2017-1000381
CVE-Crit: HIGH
CVE-DESC: The c-ares ares_parse_naptr_reply () function, which is used for parsing NAPTR responses, can be run to read memory beyond the specified input buffer if the response packet passed to DNS was created in a certain way.
CVE-STATUS: Default
CVE-REV: Default

CVE-ID: CVE-2020-8277
CVE-Crit: HIGH
CVE-DESC: A Node.js application that allows an attacker to initiate a DNS query for a host of their choice can cause a denial of service in versions <15.2.1, <14.15.1, and <12.19.1 by getting the application to resolve a DNS record with a large number of responses. This is fixed in 15.2.1, 14.15.1, and 12.19.1.
