+Subject: [PATCH] CVE-2024-56406: Heap-buffer-overflow with tr//
+
+This was due to underallocating needed space.  If the translation forces
+something to become UTF-8 that is initially bytes, that UTF-8 could
+now require two bytes where previously a single one would do.
+
+(cherry picked from commit f93109c8a6950aafbd7488d98e112552033a3686)
