Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel (Operating System). Affected is the function mmap. The manipulation with an unknown input leads to a access control vulnerability. CWE is classifying the issue as CWE-264. This is going to have an impact on availability. CVE summarizes:

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.

The bug was discovered 05/09/2008. The weakness was presented 05/15/2008 by Michael Kerrisk with Kernel.org (Website). The advisory is shared for download at kernel.org. This vulnerability is traded as CVE-2008-2148 since 05/12/2008. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1068.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 309 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 36653 (Mandriva Linux Security Advisory : kernel (MDVSA-2008:167)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165028 (SUSE Security Update for Kernel (SUSE-SA:2008:030)).
