CVE-2023-25139 Information

Description

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 1234567 (with padding to 13) overflows by two bytes.
