CVE-2008-2148

Publication date 12 May 2008

Last updated 24 July 2024


Ubuntu priority

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.

From the Ubuntu Security Team

The sys_utimensat system call did not correctly check file permissions in certain situations. A local attacker could exploit this to modify the file times of arbitrary files which could lead to a denial of service.
