Arbitrary Code Execution (ACE) Vulnerability

Bundled Perl script Spreadsheet::ParseExcel version 0.65 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. Fixed with the depreation of Excel-related functionality from gdata version 3.0.0 – upgrading advised.
