======================================================
Name: CVE-2008-2148
Status: Candidate
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2148
Reference: CONFIRM:http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.25.y.git;a=commit;h=f9dfda1ad0637a89a64d001cf81478bd8d9b6306


The utimensat system call 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.
