Description:
A weakness has been discovered in Apple Safari, which can be exploited by malicious people to cause a DoS (Denial of Service).
The weakness is caused due to a use-after-free error while calling the "servePendingRequests()" function in WebKit. This can be exploited to dereference invalid memory and cause a crash when a user visits a specially crafted web page.
Successful exploitation crashes the browser. However, even though code execution has not been proven, it cannot be completely ruled out.
NOTE: Secunia normally does not classify a browser crash as a vulnerability nor issue an advisory about it. However, the potential impact of this issue may be more severe than currently believed.
The weakness is confirmed in Apple Safari version 4.0 (530.17) for Windows. Other versions may also be affected.
