+  CVE-2023-25139: When the printf family of functions is called with a
+  format specifier that uses an <apostrophe> (enable grouping) and a
+  minimum width specifier, the resulting output could be larger than
+  reasonably expected by a caller that computed a tight bound on the
+  buffer size.  The resulting larger than expected output could result
+  in a buffer overflow in the printf family of functions.
