Description Laura Pardo 2018-04-12 23:23:35 UTC 
A flaw was found in QPDF through 8.0.2. libqpdf.a 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.
