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. libqpdf.a en QPDF hasta la versión 8.0.2 gestiona de manera incorrecta ciertos casos de "clave de diccionario esperada pero objeto sin nombre encontrado". Esto permite que los atacantes remotos provoquen una denegación de servicio (agotamiento de la pila), relacionado con las clases QPDFObjectHandle y QPDF_Dictionary. Esto se debe a que la anidación en los objetos directos no está restringida. • https://github.com/qpdf/qpdf/commit/b4d6cf6836ce025ba1811b7bbec52680c7204223 https://github.com/qpdf/qpdf/issues/202 https://usn.ubuntu.com/3638-1 • CWE-674: Uncontrolled Recursion •
