Debian Security Advisory DSA-3924-1                   security@debian.org

Package        : varnish
CVE ID         : not yet assigned
Debian Bug     : 870467

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.
