How to fix?

Upgrade Debian:11 haproxy to version 1.4.24-1 or higher.

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:11 relevant fixed versions and status.

HAProxy 1.4 before 1.4.24 and 1.5 before 1.5-dev19, when configured to use hdr_ip or other "hdr_*" functions with a negative occurrence count, allows remote attackers to cause a denial of service (negative array index usage and crash) via an HTTP header with a certain number of values, related to the MAX_HDR_HISTORY variable.
