Revision: 01
CVE Names: CVE-2023-39318
====================================================================
Summary:
Secondary Scheduler Operator for Red Hat OpenShift 1.2.0
Description:
The Secondary Scheduler Operator for Red Hat OpenShift is an optional
operator that makes it possible to deploy a secondary scheduler by
providing a scheduler image. You can run a scheduler with custom
plugins without applying additional manifests, such as cluster roles
and deployments.
Security Fix(es):
golang: net/http, x/net/http2: rapid stream resets can cause excessive work (CVE-2023-39325)
HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (CVE-2023-44487)
golang: html/template: improper handling of HTML-like comments within script contexts (CVE-2023-39318)
golang: html/template: improper handling of special tags within script contexts (CVE-2023-39319)
golang: crypto/tls: panic when processing post-handshake message on QUIC connections (CVE-2023-39321)
golang: crypto/tls: lack of a limit on buffered post-handshake (CVE-2023-39322)

A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see ...
