Update Information:

New upstream release: A security release. This release includes fix for
CVE-2022-45059 (VSV00011) and CVE-2022-45060 (VSV00010). From the upstream
release notes: VSV00010 Varnish Request Smuggling Vulnerability Date:
2022-11-08 A request smuggling attack can be performed on Varnish Cache servers
by requesting that certain headers are made hop-by-hop, preventing the Varnish
Cache servers from forwarding critical headers to the backend. Among the headers
that can be filtered this way are both Content-Length and Host, making it
possible for an attacker to both break the HTTP/1 protocol framing, and bypass
request to host routing in VCL. VSV00011 Varnish HTTP/2 Request Forgery
Vulnerability Date: 2022-11-08 A request forgery attack can be performed on
Varnish Cache servers that have the HTTP/2 protocol turned on. An attacker may
introduce characters through the HTTP/2 pseudo-headers that are invalid in the
context of an HTTP/1 request line, causing the Varnish server to produce invalid
HTTP/1 requests to the backend. This may in turn be used to successfully exploit
vulnerabilities in a server behind the Varnish server.
