Detail

Felix Wilhelm of Google Project Zero discovered that HAProxy, a TCP/HTTP reverse proxy, did not properly handle HTTP/2 headers. This would allow an attacker to write arbitrary bytes around a certain location on the heap, resulting in denial-of-service or potential arbitrary code execution.

For the stable distribution (buster), this problem has been fixed in version 1.8.19-1+deb10u2.

We recommend that you upgrade your haproxy packages.
