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...

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: golang.org/x/net/http2: golang: flow control limit bypass via double refund in HTTP/2 server

A flaw was found in Go's HTTP/2 server implementation. A remote attacker can bypass connection-level flow control limits—mechanisms that regulate incoming network data—potentially causing excessive memory consumption and a Denial of Service DoS. This issue occurs because the server improperly...

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: 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: 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...

Important: Red Hat Security Advisory: go-toolset:rhel8 security, bug fix, and enhancement update

An update for the go-toolset:rhel8 module is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each...

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...
