Descriptions
The befs_follow_link function in fs/befs/linuxvfs.c in the Linux kernel before 3.1-rc3 does not validate the length attribute of long symlinks, which allows local users to cause a denial of service (incorrect pointer dereference and OOPS) by accessing a long symlink on a malformed Be filesystem.
La función befs_follow_link en fs/befs/linuxvfs.c en el Kernel de Linux anterior a v 3.1-rc3 no valida el atributo longitud de enlaces simbólicos, lo que permite a usuarios locales provocar una denegación de servicio (desreferencia a puntero incorrecta y OOPS) accediendo a un largo enlace simbólico en un fichero de sistema mal formados.
