CVE-2017-12595 (GCVE-0-2017-12595)

Vulnerability from cvelistv5 – Published: 2017-08-27 15:00 – Updated: 2024-08-05 18:43

Summary

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.

Severity

No CVSS data available.
