Description
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.
