As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Race condition in WebKit in Apple iOS before 6.0.1 and Safari before 6.0.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving JavaScript arrays.

The weakness was presented 05/16/2013 by Joost Pol and Daan Keuper (TippingPoint) with Certified Secure working as HT5766 as confirmed advisory (Website) via ZDI (Zero Day Initiative). The advisory is shared at support.apple.com. This vulnerability is known as CVE-2012-3748 since 06/19/2012. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Vitaliy Toropov and been published 4 months after the advisory. It is possible to download the exploit at exploit-db.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 69879 (Mac OS X : Apple Safari < 5.1.10 Memory Corruptions), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 121455 (Apple Safari 5.1.10 Not Installed (APPLE-SA-2013-06-04-2)).
