Descriptions

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.

El tokenizador en QPDF 6.0.0 y 7.0.b1 es recursivo para los arrays y diccionarios, lo que permite a los atacantes remotos provocar una denegación de servicio (consumo de pila y error de segmentación) o causar otro impacto no especificado mediante un documento PDF con una estructura de datos profunda, tal y como se puede comprobar con un fallo en QPDFObjectHandle::parseInternal en libqpdf/QPDFObjectHandle.cc.

It was discovered that QPDF incorrectly handled certain malformed files. A remote attacker could use this issue to cause QPDF to crash, resulting in a denial of service, or possibly execute arbitrary code.
