Published

In github.com/xuri/excelize/v2, the streaming worksheet reader used by Rows and GetRows does not enforce the maximum row limit (TotalRows) on row "r" attributes. A crafted spreadsheet with an out-of-bounds row index causes GetRows to allocate empty row slices up to the specified row number, leading to excessive memory consumption and denial of service.
