-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2022-babfbc2622 2022-11-23 01:19:08.440331 --------------------------------------------------------------------------------
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. -------------------------------------------------------------------------------- ChangeLog:
