This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple WebKit. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists in the handling of attr() functions in a CSS content object. When a large numerical value is passed as the argument to the attr() function, a memory corruption will occur which can be leveraged to execute arbitrary coder under the context of the current user.
