DSA-190-1 wmaker -- desbordamiento de búfer

Fecha del informe:

7 de nov de 2002

Paquetes afectados:

wmaker

Vulnerable:

Sí

Referencias a bases de datos de seguridad:

En el diccionario CVE de Mitre: CVE-2002-1277.

Información adicional:

Al Viro encontró un problema en el código de gestión de imágenes usado en Window Maker, un popular gestor de ventanas similar a NEXTSTEP. Al crear una imagen, podía ubicar un búfer para multiplicar el ancho y el largo de la imagen, pero no verificaba los desbordamientos. Esto hacía posible desbordar el búfer. Esto se podía explotar usando archivos de imagen especialmente modificados (por ejemplo, al hacer la vista preliminar de los temas).

Este problema se ha corregido en la versión 0.80.0-4.1 para la distribución estable actual (woody). Los paquetes para la arquitectura mipsel aún no están disponibles.

Arreglado en:

Debian GNU/Linux 3.0 (woody)
