CVE-2017-12595 (opens in a new tab)How to fix?
Upgrade Ubuntu:16.04 qpdf to version 8.0.2-3~16.04.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream qpdf package and not the qpdf package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
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.
