DSA-207-1 tetex-bin -- ejecución de comando arbitrario

Fecha del informe:
11 de dic de 2002
Paquetes afectados:
tetex-bin
Vulnerable:
Referencias a bases de datos de seguridad:
En el diccionario CVE de Mitre: CVE-2002-0836.
Información adicional:

El equipo de seguridad de SuSE descubrió una vulnerabilidad en la biblioteca kpathsea (libkpathsea), que se usa en los paquetes xdvi y dvips. Ambos programas llamaban de forma insegura a la función system(), lo que permitía que un atacante remoto ejecutara comandos arbitrarios vía archivos DVI adecuadamente modificados.

Si se usaba dvips en un filtro de impresión, esto permitía a un atacante con permiso para imprimir ejecutar código arbitrario como el usuario printer (normalmente lp).

Este problema se ha corregido en la versión 1.0.7+20011202-7.1 para la distribución estable actual (woody), en la versión 1.0.6-7.3 para la distribución estable anterior (potato) y en la versión 1.0.7+20021025-4 para la distribución inestable (sid). xdvik-ja y dvipsk-ja son vulnerables también, pero al enlazarse dinámicamente con la biblioteca kpathsea se corregirá automáticamente tras instalar la nueva librería libkpathsea.

Le recomendamos que actualice inmediatamente su paquete tetex-lib.

Arreglado en:

Debian GNU/Linux 2.2 (potato)
