Descriptions

The error-reporting functionality in (1) fs/ext2/dir.c, (2) fs/ext3/dir.c, and possibly (3) fs/ext4/dir.c in the Linux kernel 2.6.26.5 does not limit the number of printk console messages that report directory corruption, which allows physically proximate attackers to cause a denial of service (temporary system hang) by mounting a filesystem that has corrupted dir->i_size and dir->i_blocks values and performing (a) read or (b) write operations. NOTE: there are limited scenarios in which this crosses privilege boundaries.

La funcionalidad de error de informe en (1) fs/ext2/dir.c, (2) fs/ext3/dir.c, y posiblemente en (3) fs/ext4/dir.c en el kernet de Linux v2.6.26.5 no limita el número de mensajes de consola printk que informa de la corrupción de directorio, lo cual permite a atacantes aproximarse físicamente para causar denegación de servicio (cuelgue temporal del sistema) montando un archivo de sistema corrupto con valores dir->i_size y dir->i_blocks e interpretando operaciones de (a) lectura o (b) escritura. NOTA: hay escenarios limitados en los cuales estos cruzan los límites de privilegios.
