In QPDF 8.2.1, in libqpdf/QPDFWriter.cc, QPDFWriter::unparseObject and QPDFWriter::unparseChild have recursive calls for a long time, which allows remote attackers to cause a denial of service via a crafted PDF file.
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
