NVD Description

Note: Versions mentioned in the description apply only to the upstream catdoc package and not the catdoc package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
