Hi,

The following vulnerability was published for libspreadsheet-parseexcel-perl.
The writeup[2] contains a descrption of the issue and pocs. Note that
the issue in Spreadsheet::ParseExcel will affect as well
Spreadsheet::ParseXLSX relying on Spreadsheet::ParseExcel but AFAIU,
the issue needs to be fixed in Spreadsheet::ParseExcel.

CVE-2023-7101[0]:
| Spreadsheet::ParseExcel version 0.65 is a Perl module used for
| parsing Excel files. Spreadsheet::ParseExcel is vulnerable to an
| arbitrary code execution (ACE) vulnerability due to passing
| unvalidated input from a file into a string-type “eval”.
| Specifically, the issue stems from the evaluation of Number format
| strings (not to be confused with printf-style format strings) within
| the Excel parsing logic.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
