CVE-2009-2419 · published 17 years ago
Summary

Safari versions 4.0 and 4.0.1 may stop working or execute unwanted code when a specially crafted web page is opened. The problem is caused by the browser mishandling a zero‑length JavaScript file during a reload operation. Updating Safari to a newer version or applying the vendor’s security update resolves the risk.

Use-after-free vulnerability in the servePendingRequests function in WebCore in WebKit in Apple Safari 4.0 and 4.0.1 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted HTML document that references a zero-length .js file and the JavaScript reload function. NOTE: some of these details are obtained from third party information.
