Alpine: multiple lighttpd packages: security update to 1.4.81-r0
high Tenable Cloud Security Plugin ID 435496
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- A mismatch caused by client-triggered server-sent stream resets between HTTP/2 specifications and the
internal architectures of some HTTP/2 implementations may result in excessive server resource consumption
leading to denial-of-service (DoS). By opening streams and then rapidly triggering the server to reset
them—using malformed frames or flow control errors—an attacker can exploit incorrect stream accounting.
Streams reset by the server are considered closed at the protocol level, even though backend processing
continues. This allows a client to cause the server to handle an unbounded number of concurrent streams on
a single connection. This CVE will be updated as affected product details are released. (CVE-2025-8671)
