go1.20.9 (released 2023-10-05) includes one security fixes to the cmd/go package,as well as bug fixes to the go command and the linker. See the Go 1.20.9milestone on our issue tracker for details:https://github.com/golang/go/issues?q=milestone%3AGo1.20.9+label%3ACherryPickApprovedfull diff:golang/go@go1.20.8...go1.20.9From the security mailing:[security] Go 1.21.2 and Go 1.20.9 are releasedHello gophers,We have just released Go versions 1.21.2 and 1.20.9, minor point releases.These minor releases include 1 security fixes following the security policy:- cmd/go: line directives allows arbitrary execution during build  "//line" directives can be used to bypass the restrictions on "//go:cgo_"  directives, allowing blocked linker and compiler flags to be passed during  compliation. This can result in unexpected execution of arbitrary code when  running "go build". The line directive requires the absolute path of the file in  which the directive lives, which makes exploting this issue significantly more  complex.

go1.20.10 (released 2023-10-10) includes a security fix to the net/http package.See the Go 1.20.10 milestone on our issue tracker for details:https://github.com/golang/go/issues?q=milestone%3AGo1.20.10+label%3ACherryPickApprovedfull diff:golang/go@go1.20.9...go1.20.10From the security mailing:[security] Go 1.21.3 and Go 1.20.10 are releasedHello gophers,We have just released Go versions 1.21.3 and 1.20.10, minor point releases.These minor releases include 1 security fixes following the security policy:- net/http: rapid stream resets can cause excessive work  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 to 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.  HTTP/2 servers now bound the number of simultaneously executing  handler goroutines to the stream concurrency limit. 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 v0.17.0,  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 the Server.MaxConcurrentStreams  setting and the ConfigureServer function.  This isCVE-2023-39325 and Go issuehttps://go.dev/issue/63417.  This is also tracked byCVE-2023-44487.Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
