Title
catdoc through 0.95 Out-of-Bounds Read in xls2csv MULRK Record Handler
Summary
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.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
