Descriptions

The ext4_fill_super function in fs/ext4/super.c in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 does not validate the superblock configuration, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) by attempting to mount a crafted ext4 filesystem.

La superfunción ext4_fill_super en fs/ext4/super.c del kernel Linux v2.6.27 anteriores a v2.6.27.19 y v2.6.28 anteriores a v2.6.28.7 no valida la configuración de superbloque, lo que permite a usuarios locales provocar una denegación de servicio (un puntero de referencia NULL y OOPS) mediante el intento de montar un sistema de ficheros ext4 manipulado.
