    Package        : varnish     Version        : 6.1.1-1+deb10u4     CVE ID         : CVE-2020-11653 CVE-2022-45060     Debian Bug     : 956307 1023751

    Martin van Kervel Smedshammer discovered 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.

    For Debian 10 buster, these problems have been fixed in version     6.1.1-1+deb10u4.

    We recommend that you upgrade your varnish packages.
