Descriptions
The ext4_isize function in fs/ext4/ext4.h in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 uses the i_size_high structure member during operations on arbitrary types of files, which allows local users to cause a denial of service (CPU consumption and error-message flood) by attempting to mount a crafted ext4 filesystem.
La función ext4_isize en fs/ext4/ext4.h del kernel de Linux v2.6.27 anteriores a v2.6.27.19 y v2.6.28 anteriores a v2.6.28.7 utiliza el componente de la estructura i_size_high sobre tipos de ficheros de su elección, lo que permite a usuarios locales provocar una denegación de servicio (consumo de CPU y la inundación de mensajes de error) por tratar de montar un sistema de archivos ext4 manipulado.
