net/http: Denial of Service vulnerabilities in the HTTP/2 implementation
net/http and golang.org/x/net/http2 servers that accept direct connections from
untrusted clients could be remotely made to allocate an unlimited amount of
memory, until the program crashes. Servers will now close connections if the
send queue accumulates too many control messages.
The issues are CVE-2019-9512 and CVE-2019-9514, and Go issue golang.org/issue/33606.
Thanks to Jonathan Looney from Netflix for discovering and reporting these issues.
This is also fixed in version v0.0.0-20190813141303-74dc4d7220e7 of
golang.org/x/net/http2.
net/url: parsing validation issue
url.Parse would accept URLs with malformed hosts, such that the Host field
could have arbitrary suffixes that would appear in neither Hostname() nor
Port(), allowing authorization bypasses in certain applications. Note that URLs
with invalid, not numeric ports will now return an error from url.Parse.
The issue is CVE-2019-14809 and Go issue golang.org/issue/29098.
Thanks to Julian Hector and Nikolai Krein from Cure53, and Adi Cohen (adico.me)
for discovering and reporting this issue.
go1.11.11 (released 2019/06/11) includes a fix to the crypto/x509 package.
See the Go 1.11.11 milestone on our issue tracker for details.
go1.11.12 (released 2019/07/08) includes fixes to the compiler and the linker.
See the Go 1.11.12 milestone on our issue tracker for details.
This release includes fixes to the compiler, the linker, the go command, the
runtime, and the os package.
While here, remove pkg/bootstrap from the package, as it is only used
for bootstrapping.
go1.11.7 (released 2019/04/05) includes fixes to the runtime and the net
packages. See the Go 1.11.7 milestone on our issue tracker for details.
go1.11.8 (released 2019/04/08) was accidentally released without its intended
fix. It is identical to go1.11.7, except for its version number. The intended
fix is in go1.11.9.
go1.11.9 (released 2019/04/11) fixes an issue where using the prebuilt binary
releases on older versions of GNU/Linux led to failures when linking programs
that used cgo. Only Linux users who hit this issue need to update.
go1.11.6 (released 2019/03/14) includes fixes to cgo, the compiler, linker,
runtime, go command, and the crypto/x509, encoding/json, net, and net/url
packages. See the Go 1.11.6 milestone on our issue tracker for details.
This release addresses a recently supported security issue. This DoS
vulnerability in the crypto/elliptic implementations of the P-521 and P-384
elliptic curves may let an attacker craft inputs that consume excessive
amounts of CPU.
These inputs might be delivered via TLS handshakes, X.509 certificates, JWT
tokens, ECDH shares or ECDSA signatures. In some cases, if an ECDH private
key is reused more than once, the attack can also lead to key recovery.
The issue is CVE-2019-6486 and Go issue golang.org/issue/29903.
See the Go issue for more details.
go1.11.4 (released 2018/12/14) includes fixes to cgo, the compiler, linker,
runtime, documentation, go command, and the net/http and go/types packages. It
includes a fix to a bug introduced in Go 1.11.3 that broke go get for import
path patterns containing "...". See the Go 1.11.4 milestone on our issue
tracker for details.
go1.11.3 (released 2018/12/12) includes three security fixes to "go get" and
the crypto/x509 package. See the Go 1.11.3 milestone on our issue tracker for
details.
go1.11.2 (released 2018/11/02) includes fixes to the compiler, linker,
documentation, go command, and the database/sql and go/types packages. See the
Go 1.11.2 milestone on our issue tracker for details.
go1.11.1 (released 2018/10/01) includes fixes to the compiler, documentation,
go command, runtime, and the crypto/x509, encoding/json, go/types, net,
net/http, and reflect packages. See the Go 1.11.1 milestone on our issue
tracker for details.
Also correct the PLIST and use ln -sf instead of ln -s.
This installs the go tool as go111; all the supporting files go under
$PREFIX/go111, so it does not conflict with other Go versions. Go packages
in pkgsrc do not use it to build yet.
Changes:
There are many changes and improvements to the toolchain, runtime, and
libraries, but two features stand out as being especially exciting: modules
and WebAssembly support.
This release adds preliminary support for a new concept called "modules," an
alternative to GOPATH with integrated support for versioning and package
distribution. Module support is considered experimental, and there are still
a few rough edges to smooth out, so please make liberal use of the issue
tracker.
Go 1.11 also adds an experimental port to WebAssembly (js/wasm). This allows
programmers to compile Go programs to a binary format compatible with four
major web browsers.
