CVE-2015-9252 WRITEUP MEDIUM WRITEUP
qpdf < 7.0.0 - Denial of Service via Endless Recursion in QPDFTokenizer::resolveLiteral()
An issue was discovered in QPDF before 7.0.0. Endless recursion causes stack exhaustion in QPDFTokenizer::resolveLiteral() in QPDFTokenizer.cc, related to the QPDF::resolve function in QPDF.cc.
CVSS 5.5
CVE-2017-12595 WRITEUP HIGH WRITEUP
qpdf 6.0.0 and 7.0.b1 - Denial of Service via Deep PDF Data Structure
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.
CVSS 7.8
CVE-2018-9918 WRITEUP HIGH WRITEUP
qpdf < 8.0.2 - Denial of Service via Uncontrolled Recursion in QPDFObjectHandle
libqpdf.a in QPDF through 8.0.2 mishandles certain "expected dictionary key but found non-name object" cases, allowing remote attackers to cause a denial of service (stack exhaustion), related to the QPDFObjectHandle and QPDF_Dictionary classes, because nesting in direct objects is not restricted.
CVSS 7.8
