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.

The HTTP/2 implementation in HAProxy before 2.0.10 mishandles headers, as demonstrated by carriage return (CR, ASCII 0xd), line feed (LF, ASCII 0xa), and the zero character (NUL, ASCII 0x0), aka Intermediary Encapsulation Attacks.
