CVE-2015-3258

Desbordamiento del buffer basado en memoria dinámica en la función WriteProlog en filter/texttopdf.c en texttopdf en cups-filters antes del 1.0.70, que permite a atacantes remotos provocar una denegación de servcio (colapso) o la posibilidad de ejecutar código arbitrario a través de una línea larga que contiene caracteres anchos en una tarea de impresión.

A heap-based buffer overflow was discovered in the way the texttopdf utility of cups-filter processed print jobs with a specially crafted line size. An attacker able to submit print jobs could use this flaw to crash texttopdf or, possibly, execute arbitrary code with the privileges of the "lp" user.

The cups-filters packages contain back ends, filters, and other software that was once part of the core Common UNIX Printing System distribution but is now maintained independently. A heap-based buffer overflow flaw and an integer overflow flaw leading to a heap-based buffer overflow were discovered in the way the texttopdf utility of cups-filter processed print jobs with a specially crafted line size. An attacker able to submit print jobs could use these flaws to crash texttopdf or, possibly, execute arbitrary code with the privileges of the "lp" user.
