+Subject: [PATCH] [release-branch.go1.19] cmd/go: disallow package directories
+ containing newlines
+
+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.
+
+Updates #60167.
+Fixes #60515.
+Fixes CVE-2023-29402.

+Subject: [PATCH] [release-branch.go1.19] cmd/go: enforce flags with
+ non-optional arguments
+
+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.
