Descriptions

There is an invalid memory access in the TextLine class in TextOutputDev.cc in Xpdf 4.0.4 because the text extractor mishandles characters at large y coordinates. It can be triggered by (for example) sending a crafted pdf file to the pdftotext binary, which allows a remote attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact.

Se presenta un acceso no válido a la memoria en la clase TextLine en el archivo TextOutputDev.cc en Xpdf versión 4.0.4, porque el extractor de texto maneja inapropiadamente los caracteres en coordenadas y grandes. Puede desencadenarse (por ejemplo) mediante el envío de un archivo pdf diseñado al binario pdftotext, lo que permite a un atacante remoto causar una Denegación de Servicio (fallo de segmentación) o posiblemente tener otro impacto no especificado
