Detailsinfo

A vulnerability was found in Linux Kernel 2.6.16.9 (Operating System). It has been classified as problematic. Affected is an unknown code. The manipulation with an unknown input leads to a resource management vulnerability. CWE is classifying the issue as CWE-399. This is going to have an impact on availability. CVE summarizes:

The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation in the Linux kernel before 2.6.25.15 do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory, which allows local users to cause a denial of service ("overflow" of the UBIFS orphan area) via a series of attempted file creations within deleted directories.

The bug was discovered 08/06/2008. The weakness was released 08/12/2008 (Website). The advisory is shared for download at lkml.org. This vulnerability is traded as CVE-2008-3275 since 07/24/2008. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 876 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 67790 (Oracle Linux 4 : kernel (ELSA-2009-0014)), which helps to determine the existence of the flaw in a target environment.
