CVE-2023-25139

sprintf in the GNU C Library (glibc) 2.37 has a buffer overflow
(out-of-bounds write) in some situations with a correct buffer size. This
is unrelated to CWE-676. It may write beyond the bounds of the destination
buffer when attempting to write a padded, thousands-separated string
representation of a number, if the buffer is allocated the exact size
required to represent that number as a string. For example, 1,234,567 (with
padding to 13) overflows by two bytes.
