CVE-2018-9918
First published: Tue Apr 10 2018(Updated: )
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.
