The Gfx::getPos function in the PDF parser in xpdf before 3.02pl5, poppler 0.8.7 and possibly other versions up to 0.15.1, CUPS, kdegraphics, and possibly other products allows context-dependent attackers to cause a denial of service (crash) via unknown vectors that trigger an uninitialized pointer dereference.

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.
Severity: MEDIUM
