Databento Binary Encoding (DBN) has a heap buffer overflow using c_chars_to_str function
The heap-buffer-overflow is triggered in the strlen() function when handling the c_chars_to_str function in the dbn crate. This vulnerability occurs because the CStr::from_ptr() function in Rust assumes that the provided C string is null-terminated. However, there is no guarantee that the input chars array passed to the c_chars_to_str function is properly null-terminated. If the chars array does not contain a null byte (\0), strlen() will continue to read beyond the …
