  - FPE in the function PostScriptFunction::exec at Function.cc for the psOpIdiv case

  - FPE in the function PSOutputDev::checkPageSlice at PSOutputDev.cc for nStripes

  - FPE in the function Splash::scaleImageYuXu at Splash.cc for x Bresenham parameters

  - FPE in the function ImageStream::ImageStream at Stream.cc for nComps

  - NULL pointer dereference in the function Gfx::opSetExtGState in Gfx.cc

  - FPE in the function PostScriptFunction::exec at Function.cc for the psOpMod case

  - FPE in the function Splash::scaleImageYuXu at Splash.cc for y Bresenham parameters

  - FPE in the function ImageStream::ImageStream at Stream.cc for nBits

  - FPE in the function PostScriptFunction::exec in Function.cc for the psOpRoll case

  - A buffer over-read could be triggered in FOFIType1C::convertToType1 in fofi/FoFiType1C.cc when
    the index number is larger than the charset array bounds. It can, for example, be triggered by
    sending a crafted PDF document to the pdftops tool. It allows an attacker to use a crafted PDF file
    to cause a Denial of Service or an information leak, or possibly have unspecified other impact.

  - A heap-based buffer over-read could be triggered in FoFiType1C::convertToType0 in fofi/FoFiType1C.cc when
    it is trying to access the second privateDicts array element, because the array has only one element allowed.

  - integer overflow in the function JBIG2Bitmap::combine at JBIG2Stream.cc for the 'one byte per line' case

  - integer overflow in the function JBIG2Bitmap::combine at JBIG2Stream.cc for the 'multiple bytes per line' case

  - out of bounds read in the function GfxPatchMeshShading::parse at GfxState.cc for typeA==6 case 2

  - out of bounds read in the function GfxPatchMeshShading::parse at GfxState.cc for typeA==6 case 3

  - out of bounds read in the function GfxPatchMeshShading::parse at GfxState.cc for typeA!=6 case 1

  - out of bounds read in the function GfxPatchMeshShading::parse at GfxState.cc for typeA!=6 case 2

  - use-after-free in the function JPXStream::fillReadBuf at JPXStream.cc due to an out of bounds read");
