--------------------------------------------------------------------------------
Name : varnish
Product : Fedora 36
Version : 7.0.3
Release : 2.fc36
URL : https://www.varnish-cache.org/
Summary : High-performance HTTP accelerator
Description :
This is Varnish Cache, a high-performance HTTP accelerator.
Varnish Cache stores web pages in memory so web servers don���t have to
create the same web page over and over again. Varnish Cache serves
pages much faster than any application server; giving the website a
significant speed up.
Documentation wiki and additional information about Varnish Cache is
available on: https://www.varnish-cache.org/

Update Information:
This release includes fix for CVE-2022-45059 (VSV00010) and CVE-2022-45060
(VSV00011). 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.
