NVD Description
Note: Versions mentioned in the description apply only to the upstream haproxy package and not the haproxy package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
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.
