Package        : haproxy
CVE ID         : CVE-2020-11100

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.
