Title: PHP Out-of-bounds Read Vulnerability
Overview:

An issue was discovered in PHP 7.x before 7.1.26 7.2.x before 7.2.14 and 7.3.x before 7.3.2. dns_get_record misparses a DNS response which can allow a hostile DNS server to cause PHP to misuse memcpy leading to read operations going past the buffer allocated for DNS data. This affects php_parserr in ext/standard/dns.c for DNS_CAA and DNS_ANY queries.
