An issue was discovered in Poppler 0.71.0. There is a NULL pointer dereference in goo/GooString.h, will lead to denial of service, as demonstrated by utils/pdfdetach.cc not validating a filename of an embedded file before constructing a save path.
The product dereferences a pointer that it expects to be valid but is NULL.
