Exploitation Summary

EIP tracks 1 public exploit for CVE-2010-0105. PoCs published by Maksymilian Arciemowicz.

AI-analyzed exploit summary This exploit triggers a denial-of-service condition in MacOS X 10.6 HFS file system by creating a deeply nested directory structure with hard links, causing filesystem verification tools to fail. The PoC demonstrates the vulnerability by exhausting the maximum nesting limit of directories and directory hard links.

Description

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.
