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)
