Detailsinfo

A vulnerability, which was classified as problematic, was found in Microsoft Windows up to 2000 (Operating System). Affected is the function api in the library ntdll.dll. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on integrity. CVE summarizes:

The RtlDosPathNameToNtPathName_U API function in NTDLL.DLL in Microsoft Windows 2000 SP4 and XP SP2 does not properly convert DOS style paths with trailing spaces into NT style paths, which allows context-dependent attackers to create files that cannot be accessed through the expected DOS path or prevent access to other similarly named files in the same directory, which prevents those files from being detected or disinfected by certain anti-virus and anti-spyware software.

The weakness was published 05/10/2006 by Mario Ballano as not defined posting (Bugtraq). The advisory is shared for download at securityfocus.com. This vulnerability is traded as CVE-2006-2334 since 05/11/2006. The exploitability is told to be easy. The attack needs to be approached locally. A authentication is necessary for exploitation. Technical details and a public exploit are known.
