Includes security fixes for net/http (CVE-2022-41717, CVE-2022-41720),
and os (CVE-2022-41720).
These minor releases include 2 security fixes following the security policy:
- os, net/http: avoid escapes from os.DirFS and http.Dir on Windows
The os.DirFS function and http.Dir type provide access to a tree of files
rooted at a given directory. These functions permitted access to Windows
device files under that root. For example, os.DirFS("C:/tmp").Open("COM1")
would open the COM1 device.
Both os.DirFS and http.Dir only provide read-only filesystem access.
In addition, on Windows, an os.DirFS for the directory \(the root of the
current drive) can permit a maliciously crafted path to escape from the
drive and access any path on the system.
The behavior of os.DirFS("") has changed. Previously, an empty root was
treated equivalently to "/", so os.DirFS("").Open("tmp") would open the
path "/tmp". This now returns an error.
This is CVE-2022-41720 and Go issue https://go.dev/issue/56694.
- net/http: limit canonical header cache by bytes, not entries
An attacker can cause excessive memory growth in a Go server accepting
HTTP/2 requests.
HTTP/2 server connections contain a cache of HTTP header keys sent by
the client. While the total number of entries in this cache is capped,
an attacker sending very large keys can cause the server to allocate
approximately 64 MiB per open connection.
This issue is also fixed in golang.org/x/net/http2 vX.Y.Z, for users
manually configuring HTTP/2.
Thanks to Josselin Costanzi for reporting this issue.
This is CVE-2022-41717 and Go issue https://go.dev/issue/56350.

On Windows, syscall.StartProcess and os/exec.Cmd did not properly
check for invalid environment variable values. A malicious
environment variable value could exploit this behavior to set a
value for a different environment variable. For example, the
environment variable string "A=B\x00C=D" set the variables "A=B" and
"C=D".

issue.
This is CVE-2022-41716 and Go issue https://go.dev/issue/56284.
This Go release also fixes https://github.com/golang/go/issues/56309, a
runtime bug which can cause random memory corruption when a goroutine
exits with runtime.LockOSThread() set. This fix is necessary to unblock
work to replace certain uses of pkg/reexec with unshared OS threads.

From the mailing list:
We have just released Go versions 1.19.2 and 1.18.7, minor point releases.
These minor releases include 3 security fixes following the security policy:
- archive/tar: unbounded memory consumption when reading headers
Reader.Read did not set a limit on the maximum size of file headers.
A maliciously crafted archive could cause Read to allocate unbounded
amounts of memory, potentially causing resource exhaustion or panics.
Reader.Read now limits the maximum size of header blocks to 1 MiB.
Thanks to Adam Korczynski (ADA Logics) and OSS-Fuzz for reporting this issue.
This is CVE-2022-2879 and Go issue https://go.dev/issue/54853.
- net/http/httputil: ReverseProxy should not forward unparseable query parameters
Requests forwarded by ReverseProxy included the raw query parameters from the
inbound request, including unparseable parameters rejected by net/http. This
could permit query parameter smuggling when a Go proxy forwards a parameter
with an unparseable value.
ReverseProxy will now sanitize the query parameters in the forwarded query
when the outbound request's Form field is set after the ReverseProxy.Director
function returns, indicating that the proxy has parsed the query parameters.
Proxies which do not parse query parameters continue to forward the original
query parameters unchanged.
Thanks to Gal Goldstein (Security Researcher, Oxeye) and
Daniel Abeles (Head of Research, Oxeye) for reporting this issue.
This is CVE-2022-2880 and Go issue https://go.dev/issue/54663.
- regexp/syntax: limit memory used by parsing regexps
The parsed regexp representation is linear in the size of the input,
but in some cases the constant factor can be as high as 40,000,
making relatively small regexps consume much larger amounts of memory.
Each regexp being parsed is now limited to a 256 MB memory footprint.
Regular expressions whose representation would use more space than that
are now rejected. Normal use of regular expressions is unaffected.

From the mailing list:
We have just released Go versions 1.19.1 and 1.18.6, minor point releases.
These minor releases include 2 security fixes following the security policy:
- net/http: handle server errors after sending GOAWAY
A closing HTTP/2 server connection could hang forever waiting for a clean
shutdown that was preempted by a subsequent fatal error. This failure mode
could be exploited to cause a denial of service.
Thanks to Bahruz Jabiyev, Tommaso Innocenti, Anthony Gavazzi, Steven Sprecher,
and Kaan Onarlioglu for reporting this.
This is CVE-2022-27664 and Go issue https://go.dev/issue/54658.
- net/url: JoinPath does not strip relative path components in all circumstances
JoinPath and URL.JoinPath would not remove `../` path components appended to a
relative path. For example, `JoinPath("https://go.dev", "../go")` returned the
URL `https://go.dev/../go`, despite the JoinPath documentation stating that
`../` path elements are cleaned from the result.

Release notes:
go1.19.1 (released 2022-09-06) includes security fixes to the net/http and
net/url packages, as well as bug fixes to the compiler, the go command, the pprof
command, the linker, the runtime, and the crypto/tls and crypto/x509 packages.
See the Go 1.19.1 milestone on the issue tracker for details.
