Descriptions

The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel before 2.6.35 uses an incorrect size value in calculations associated with sentinel directory entries, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c.

La función gfs2_dirent_find_space en fs/gfs2/dir.c en el kernel de Linux anterior a v 2.6.35, usa un valor de tamaño incorrecto en los cálculos asociados con las entradas del directorio "sentinel", lo que permite a usuarios locales provocar una denegación de servicio (deferencia a puntero nullo y kernel panic) y posiblemente otro impacto no especificados mediante el renombrado de un archivo en un sistema de fichero GFS2, relacionado con la función gfs2_rename en fs/gfs2/ops_inode.c.
