Discussion

Apple Mac OS X mDNSResponderHelper Local Format String Vulnerability

Apple Mac OS X is prone to a local format-string vulnerability. This occurs because 'mDNSResponderHelper' fails to adequately sanitize user-supplied input before passing it to a formatted-printing function.

Successfully exploiting this issue will allow local attackers to execute arbitrary machine code with superuser privileges, completely compromising the computer. Failed exploit attempts will likely result in a denial of service.

NOTE: This vulnerability was previously covered in BID 28304 (Apple Mac OS X 2008-002 Multiple Security Vulnerabilities), but has been given its own record to better document the issue.
