Descriptions

The utimensat system call (sys_utimensat) in Linux kernel 2.6.22 and other versions before 2.6.25.3 does not check file permissions when certain UTIME_NOW and UTIME_OMIT combinations are used, which allows local users to modify file times of arbitrary files, possibly leading to a denial of service.

Una llamada de sistema utimensat (sys_utimensat) en el Kernel de Linux versión 2.6.22 y otras versiones anteriores a 2.6.25.3, no comprueba los permisos de los archivos cuando son usadas ciertas combinaciones UTIME_NOW y UTIME_OMIT, lo que permite a los usuarios locales modificar los tiempos de archivos arbitrarios, posiblemente conllevando a una denegación de servicio.
