Apple Mac OS X AppleScript Remote Format String Vulnerability

Apple Mac OS X is prone to format-string vulnerability because it fails to properly sanitize user-supplied input before passing it as a format specifier to a formatted-printing function.

An attacker may exploit this issue to execute arbitrary code in the context of the vulnerable AppleScript Studio-based application. Failed exploit attempts will likely result in a denial-of-service condition.

Versions prior to OS X 10.6.7 are vulnerable.

NOTE: This issue was previously discussed in BID 46950 (Apple Mac OS X Prior to 10.6.7 Multiple Security Vulnerabilities) but has been given its own record to better document it.
