on 0.9.5 (the latest version):
there is a signed integer overflow in the
PdfObjectStreamParserObject::ReadObjectsFromStream function
(src/base/PdfObjectStreamParserObject.cpp), which can cause denial of
service via a crafted pdf file.

src/base/PdfObjectStreamParserObject.cpp:99:30: runtime error: signed
integer overflow: 94 + 9223372036854775807 cannot be represented in
type 'long int'

To reproduce the issue, compile libming with UBSAN "-fsanitize=undefined",
then execute: podofoimgextract $POC OUTPUT_DIR

The POC is attached.
