+Subject: [PATCH] [release-branch.go1.20] cmd/go,cmd/cgo: in _cgo_flags use one
+ line per flag
+
+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.
+
+Updates #60306
+Fixes #60514
+Fixes CVE-2023-29405
