Detailsinfo

A vulnerability classified as problematic was found in Apple Mac OS X up to 10.5.7 (Operating System). This vulnerability affects an unknown function of the component Filesystem. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. CVE summarizes:

The hfs implementation in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 supports hard links to directories and does not prevent certain deeply nested directory structures, which allows local users to cause a denial of service (filesystem corruption) via a crafted application that calls the mkdir and link functions, related to the fsck_hfs program in the diskdev_cmds component.

The weakness was presented 04/27/2010 by Maksymilian Arciemowicz (Website). The advisory is shared for download at securitytracker.com. This vulnerability was named CVE-2010-0105 since 12/30/2009. The exploitation appears to be easy. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Maksymilian Arciemowicz in ANSI C and been published before and not just after the advisory. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 3 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 50548 (Mac OS X 10.6.x < 10.6.5 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment.
