Netpbm before 10.86.51, 11.x before 11.02.30, and 11.03 before 11.15.08 contains a stack-based buffer overflow in the picttoppm paintPoly() function due to an unbounded polygon point count. Attackers can supply a crafted PICT file with a polygon exceeding 100 points to overwrite the fixed pts array, causing crashes or potentially code execution.
