Descriptions
The gfs2_fallocate function in fs/gfs2/file.c in the Linux kernel before 3.0-rc1 does not ensure that the size of a chunk allocation is a multiple of the block size, which allows local users to cause a denial of service (BUG and system crash) by arranging for all resource groups to have too little free space.
La función gfs2_fallocate en fs/gfs2/file.c en el kernel de Linux anterior a v3.0-rc1 no garantiza que el tamaño de un trozo de asignación sea un múltiplo del tamaño de bloque, lo que permite a usuarios locales provocar una denegación de servicio (BUG y caída del sistema) mediante la organización de todos los grupos de recursos para tener un espacio libre muy reducido.
