net/http: golang.org/x/net/http2: golang: net/http: Denial of Service via HTTP/2 trailer header memory exhaustion
A flaw was found in the Go net/http package. A remote attacker can trigger a Denial of Service DoS by sending HTTP/2 requests that declare an excessive number of trailer header fields. Because the server bypasses configured header limits when allocating memory for these declarations, an attacker...
net/http: golang: golang.org/x/net/http2: net/http: HTTP response smuggling via malformed HTTP/2 framing headers
A flaw was found in Go's net/http package. When operating as a reverse proxy, the HTTP/2 implementation does not properly validate framing-related headers in responses received from upstream servers before forwarding them to downstream HTTP/1 clients. A malicious upstream server can exploit this...
net/http: net/http/internal/http2: golang.org/x/net/http2: net/http: Denial of Service via excessive HTTP/2 SETTINGS frames
A flaw was found in the Go net/http package. This flaw allows a remote attacker to cause a Denial of Service DoS by triggering excessive CPU consumption on an affected client or server. By opening a large number of HTTP/2 streams and repeatedly sending small configuration SETTINGS frames that...
net/http: net/http/internal/http2: golang: golang.org/x/net/http2: net/http: Denial of Service via concurrent HPACK encoder modification
A flaw was found in Go's net/http package. A remote attacker can cause a Denial of Service DoS by crashing the HTTP/2 server. Due to missing synchronization, the server concurrently modifies its HPACK HTTP/2 header compression encoder when encoding response headers while processing incoming table...

Red Hat Product Security has rated this update as having a security impact of Important. ...
golang: net/http: net/http: sensitive headers incorrectly sent after cross-domain redirect
A flaw was found in the net/http package of the Golang standard library. The HTTP client drops sensitive headers after following a cross-domain redirect. For example, a request to a.com/ containing an Authorization header redirected to b.com/ will not send that header to b.com. However, the...
net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service
A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...
net/http: golang.org/x/net/http2: golang: net/http: Denial of Service via HTTP/2 trailer header memory exhaustion
A flaw was found in the Go net/http package. A remote attacker can trigger a Denial of Service DoS by sending HTTP/2 requests that declare an excessive number of trailer header fields. Because the server bypasses configured header limits when allocating memory for these declarations, an attacker...
net/http: golang: golang: Denial of Service via crafted HTTP Range headers
A flaw was found in the Go net/http package. A remote attacker can cause a Denial of Service DoS by sending an HTTP request containing a Range header with a large number of small byte ranges. When the server processes these ranges while serving content, it consumes an excessive amount of CPU...
net/http: net/http/internal/http2: golang.org/x/net/http2: net/http: Denial of Service via excessive HTTP/2 SETTINGS frames
A flaw was found in the Go net/http package. This flaw allows a remote attacker to cause a Denial of Service DoS by triggering excessive CPU consumption on an affected client or server. By opening a large number of HTTP/2 streams and repeatedly sending small configuration SETTINGS frames that...
net/http: golang: net/http: HTTP request smuggling via improper handling of HTTP/1 CONNECT responses
A flaw was found in Go's net/http package. When an HTTP server sends a successful response to an HTTP/1 CONNECT request without taking raw control of the connection, it improperly continues to process incoming data as standard HTTP requests instead of establishing a tunnel. A remote attacker can...
net/http: Sensitive headers not cleared on cross-origin redirect in net/http
A flaw was found in net/http. Handling Proxy-Authorization and Proxy-Authenticate headers during cross-origin redirects allows these headers to be inadvertently forwarded, potentially exposing sensitive authentication credentials. This flaw allows a network-based attacker to manipulate redirect...
net/http/internal/http2: golang: golang.org/x/net: Go HTTP/2: Denial of Service via malformed SETTINGS_MAX_FRAME_SIZE frame
A flaw was found in the HTTP/2 protocol implementation within the Go standard library golang.org/x/net and net/http/internal/http2. A remote attacker can exploit this vulnerability by sending a specially crafted HTTP/2 SETTINGS frame with the SETTINGSMAXFRAMESIZE parameter set to zero. This...
net/http: golang: golang: Cross-user response poisoning via desynchronized HTTP CONNECT connections
A flaw was found in Go's net/http package. When an HTTP CONNECT request with a request body is rejected by a server, the client transport can desynchronize the connection before returning it to the shared idle pool. In shared reverse proxy environments, a remote attacker can exploit this issue to...
