The headerplus.write_req0() function from vmod_headerplus updates the underlying req0, which is normally the original read-only request from which req is derived (readable and writable from VCL). This is useful in the active VCL, after amending req, to prepare a refined req0 before switching to a different VCL with the return (vcl(&lt;label&gt;)) action. This is for example how the Varnish Controller operates shared VCL deployments. If the amended req contained too many header fields for req0, this would have resulted in a workspace overflow that would in turn trigger a panic and crash the Varnish Enterprise server. This could be used as a Denial of Service attack vector by malicious clients.</p> <p><strong>Affected:</strong> varnish-software Varnish Enterprise</p> <p>Varnish Enterprise before 6.0.16r12 allows a &#34;workspace overflow&#34; denial of service (daemon panic) for shared VCL.
