How to fix?

There is no fixed version for RHEL:7 qpdf-doc.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qpdf-doc package and not the qpdf-doc package as distributed by RHEL. See How to fix? for RHEL:7 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.
