Descriptions

The make_indexed_dir function in fs/ext4/namei.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 a certain rec_len field, which allows local users to cause a denial of service (OOPS) by attempting to mount a crafted ext4 filesystem.

La función make_indexed_dir en fs/ext4/namei.c en el kernel de Linux v2.6.27 anteriores a v2.6.27.19 y v2.6.28 anteriores a v2.6.28.7 no valida el campo rec_len, lo que permite a usuarios locales provocar una denegación de servicio (OOPS ) por tratar de montar un sistema de archivos ext4 manipulado.
