Descriptions

Heap-based buffer overflow in the linetoken function in afmparse.c in t1lib, as used in teTeX 3.0.x, GNOME evince, and possibly other products, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a DVI file containing a crafted Adobe Font Metrics (AFM) file, a different vulnerability than CVE-2010-2642.

Un desbordamiento de búfer basado en memoria dinámica ('heap') en la función linetoken en afmparse.c en t1lib, tal y como se utiliza en teTeX v3.0.x, GNOME Evince, y posiblemente otros productos, permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) y posiblemente ejecutar código de su elección a través de un archivo que contiene un DVI que contiene un archivo Adobe Font Metrics (AFM) hecho a mano. Se trata de una vulnerabilidad diferente a CVE-2010-2642.
