From 8eddf81239a58bbdbb700c8cc46e8e671b20108c Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/4] [Backport] cmd/go: disallow package directories
containing newlines
Offering: Cloud Core Network
CVE: CVE-2023-29402
Reference: https://go-review.googlesource.com/c/go/+/501218
Directory or file paths containing newlines may cause tools (such as
cmd/cgo) that emit "//line" or "#line" -directives to write part of
the path into non-comment lines in generated source code. If those
lines contain valid Go code, it may be injected into the resulting
binary.
(Note that Go import paths and file paths within module zip files
already could not contain newlines.)
Thanks to Juho Nurminen of Mattermost for reporting this issue.
Note: The upstream does not submit this change to go1.17 according to the rules of MinorReleases.
Corego3.x are based on go1.17.8. Therefore, it need to submit the change to corego3.x.

Subject: [PATCH 3/4] [Backport] cmd/go: enforce flags with non-optional
arguments
Offering: Cloud Core Network
CVE: CVE-2023-29404
Reference: https://go-review.googlesource.com/c/go/+/501217
Enforce that linker flags which expect arguments get them, otherwise it
may be possible to smuggle unexpected flags through as the linker can
consume what looks like a flag as an argument to a preceding flag (i.e.
"-Wl,-O -Wl,-R,-bad-flag" is interpreted as "-O=-R -bad-flag"). Also be
somewhat more restrictive in the general format of some flags.
Thanks to Juho Nurminen of Mattermost for reporting this issue.

Subject: [PATCH 4/4] [Backport] cmd/go,cmd/cgo: in _cgo_flags use one line per
flag
Offering: Cloud Core Network
CVE: CVE-2023-29405
Reference: https://go-review.googlesource.com/c/go/+/501216
The flags that we recorded in _cgo_flags did not use any quoting,
so a flag containing embedded spaces was mishandled.
Change the _cgo_flags format to put each flag on a separate line.
That is a simple format that does not require any quoting.
As far as I can tell only cmd/go uses _cgo_flags, and it is only
used for gccgo. If this patch doesn't cause any trouble, then
in the next release we can change to only using _cgo_flags for gccgo.
Thanks to Juho Nurminen of Mattermost for reporting this issue.
