Descriptions

In Poppler 0.72.0, PDFDoc::setup in PDFDoc.cc allows attackers to cause a denial-of-service (application crash caused by Object.h SIGABRT, because of a wrong return value from PDFDoc::setup) by crafting a PDF file in which an xref data structure is mishandled during extractPDFSubtype processing.

En la versión 0.72.0 de Poppler, PDFDoc::setup en PDFDoc.cc permite a los atacantes remotos provocar una denegación de servicio (cierre inesperado de la aplicación provocado por un SIGABRT en Object.h debido a un valor de retorno incorrecto de PDFDoc::setup) manipulando un archivo PDF en el que la estructura de datos xref se maneja de manera incorrecta durante el procesamiento de extractPDFSubtype.

Poppler is a Portable Document Format rendering library, used by applications such as Evince or Okular. Issues addressed include buffer overflow and null pointer vulnerabilities.
