Descriptions

In Artifex MuPDF 1.13.0, the fz_append_byte function in fitz/buffer.c allows remote attackers to cause a denial of service (segmentation fault) via a crafted pdf file. This is caused by a pdf/pdf-device.c pdf_dev_alpha array-index underflow.

La función fz_append_byte en fitz/buffer.c en Artifex MuPDF 1.13.0 permite que atacantes remotos provoquen una denegación de servicio (fallo de segmentación) mediante un archivo pdf manipulado. Esto se ha provocado por un subdesbordamiento de índice de arrays pdf_dev_alpha en pdf/pdf-device.c.
