Zero Day Initiative Advisory 10-099 – This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple’s Webkit. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists with how WebKit inserts error messages into documents utilizing the SVG namespace. Upon a parsing error the library will attempt to access an element before repairing the XML. This will cause the library to access uninitialized memory which can lead to code execution under the context of the application.
