CVE-2018-20102 medium priority: Ubuntu including 1 source packages (haproxy), 5 status rows across 5 suites (bionic, cosmic, trusty, upstream, xenial): released 4, DNE 1.
An out-of-bounds read in dns_validate_dns_response in dns.c was discovered in HAProxy through 1.8.14. Due to a missing check when validating DNS responses, remote attackers might be able read the 16 bytes corresponding to an AAAA record from the non-initialized part of the buffer, possibly accessing anything that was left on the stack, or even past the end of the 8193-byte buffer, depending on the value of accepted_payload_size.
