(Xpdf, Poppler, GPdf, libextractor, pdftohtml: Heap overflows)

    Chris Evans has reported some integer overflows in Xpdf when
    attempting to calculate buffer sizes for memory allocation, leading to
    a heap overflow and a potential infinite loop when handling malformed
    input files.
  
Impact :

    By sending a specially crafted PDF file to a victim, an attacker
    could cause an overflow, potentially resulting in the execution of
    arbitrary code with the privileges of the user running the application.
  
Workaround :

    There is no known workaround at this time."
