+        Integer and memory overflow issues (Bug#9397).
+
+        * emacsclient.c (xmalloc): Accept size_t, not unsigned int, to
+        avoid potential buffer overflow issues on typical 64-bit hosts.
+        Return void *, not long *.
+        (get_current_dir_name): Report a failure, instead of looping
+        forever, if buffer size calculation overflows.  Treat malloc
+        failures like realloc failures, as that has better behavior and is
+        more consistent.  Do not check whether xmalloc returns NULL, as
+        that's not possible.
+        (message): Do not arbitrarily truncate message to 2048 bytes when
+        sending it to stderr; use vfprintf instead.
+        (get_server_config, set_local_socket)
+        (start_daemon_and_retry_set_socket): Do not alloca
+        arbitrarily-large buffers; that's not safe.
+        (get_server_config, set_local_socket): Do not use sprintf when its
+        result might not fit in 'int'.
+        (set_local_socket): Do not assume uid fits in 'int'.
+
+        * etags.c (xmalloc, xrealloc): Accept size_t, not unsigned int,
+        to avoid potential buffer overflow issues on typical 64-bit hosts.
+        (whatlen_max): New static var.
+        (main): Avoid buffer overflow if subsidiary command length is
+        greater than BUFSIZ or 2*BUFSIZ + 20. Do not use sprintf when its
+        result might not fit in 'int'.
+
+        * movemail.c (main): Do not use sprintf when its result might not fit
+        in 'int'.  Instead, put the possibly-long file name into the
+        output of pfatal_with_name.
+
+        * update-game-score.c: Include <limits.h>
+        (get_user_id): Do not assume uid fits in 'int'.  Simplify.

         Assume freestanding C89 headers, string.h, stdlib.h.
