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.
