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.

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2024:2173-1 advisory.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - qpdf: stack exhaustion in QPDFObjectHandle and QPDF_Dictionary classes in libqpdf.a (CVE-2018-9918)

  - 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.
    (CVE-2015-9252)

  - A stack-consumption vulnerability was found in libqpdf in QPDF 6.0.0, which allows attackers to cause a     denial of service via a crafted file, related to the QPDFTokenizer::resolveLiteral function in     QPDFTokenizer.cc after two consecutive calls to QPDFObjectHandle::parseInternal, aka an infinite loop.
    (CVE-2017-11624)
