Descriptions

An issue was discovered in Xpdf 4.00. catalog->getNumPages() in AcroForm.cc allows attackers to launch a denial of service (hang caused by large loop) via a specific pdf file, as demonstrated by pdftohtml. This is mainly caused by a large number after the /Count field in the file.

Se ha descubierto un problema en Xpdf 4.00. catalog->getNumPages() en AcroForm.cc permite que los atacantes provoquen una denegación de servicio (bloqueo provocado por un gran bucle) mediante un archivo PDF específico, tal y como queda demostrado con pdftohtml. Esto es provocado principalmente por un número grande tras el campo /Count en el archivo.
