function in proto_http.c (CVE-2018-11469)

* haproxy: Out-of-bounds read in dns.c:dns_validate_dns_response() allows
for memory disclosure (CVE-2018-20102)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
