CVE-2017-12595 (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-12595): The tokenizer in QPDF 6.0.0 and 7.0.b1 is recursive for arrays and dictionaries, which allows remote attackers to cause a denial of service (stack consumption and segmentation fault) or possibly have unspecified other impact via a PDF document with a deep data structure, as demonstrated by a crash in QPDFObjectHandle::parseInternal in libqpdf/QPDFObjectHandle.cc.

I just tested versions 5.1.1-r1 and 5.1.3-r1, they both return segmentation faults. This bug has been fixed in the new 7.0.0 release: 2017-08-25 Jay Berkenbilt <ejb@ql.org> * Re-implement parser iteratively to avoid stack overflow on very deeply nested arrays and dictionaries. Fixes #146. @ Maintainer(s): Please advise how you would like to proceed.
