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 protocolturned 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. --------------------------------------------------------------------------------ChangeLog: * Mon Nov 14 2022 Ingvar Hagelund - 0.20.0-4 - Built for varnish-7.1.2 --------------------------------------------------------------------------------References: [ 1 ] Bug #2141842 - CVE-2022-45059 varnish: Request Smuggling Vulnerability [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=2141842 [ 2 ] Bug #2141847 - CVE-2022-45060 varnish: Request Forgery Vulnerability [fedora-all] https://bugzilla.redhat.com/show_bug.cgi?id=2141847 --------------------------------------------------------------------------------This update can be installed with the "dnf" update program.
