    A denial of service vulnerability was discovered in Varnish, a state of
    the art, high-performance web accelerator. Specially crafted HTTP
    requests can cause the Varnish daemon to assert and restart, clearing
    the cache in the process.
    
    See https://varnish-cache.org/security/VSV00001.html for details.
    
    For the oldstable distribution (jessie), this problem has been fixed
    in version 4.0.2-1+deb8u1.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 5.0.0-7+deb9u1.
    
    We recommend that you upgrade your varnish packages.
