Integer overflow in the StreamPredictor::StreamPredictor function in xpdf 3.02, as used in (1) poppler before 0.5.91, (2) gpdf before 2.8.2, (3) kpdf, (4) kdegraphics, (5) CUPS, (6) PDFedit, and other products, might allow remote attackers to execute arbitrary code via a crafted PDF file that triggers a stack-based buffer overflow in the StreamPredictor::getNextLine function.
Category
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
