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

Multiple vulnerabilities have been found in Xpdf, the worst of which could result in denial of service. Versions greater than or equal to 4.05 are affected.
