    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.
    
    For the detailed security status of haproxy please refer to
    its security tracker page at:
