Summary
Updated varnish & lighttpd packages fix security vulnerability
Details

It was discovered that a denial of service attack can be performed on cache servers that have the HTTP/2 protocol turned on. An attacker can create a large number of streams and immediately reset them without ever reaching the maximum number of concurrent streams allowed for the session, causing the server to consume unnecessary resources processing requests for which the response will not be delivered (CVE-2025-8671).
