catdoc through 0.95 contains an out-of-bounds read vulnerability in the MULRK record handler of process_item() in src/xlsparse.c that allows attackers to read past the static rec buffer via a crafted end column. Attackers can supply a crafted .xls workbook or BIFF stream with a large endcol to xls2csv to disclose adjacent process memory as CSV cells or crash the process.
