* haproxy: Information disclosure in check_request_for_cacheability
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
page(s) listed in the References section.
