Intrusion Prevention

Firefox.OnUnload.Memory.Corruption

Description

Mozilla Firefox 1.5.0.9 and 2.0.0.1, and SeaMonkey before 1.0.8 allow remote attackers to execute arbitrary code via JavaScript onUnload handlers that modify the structure of a document, which triggers memory corruption due to the lack of a finalize hook on DOM window objects.

Affected Products

Mozilla Firefox 1.5.0.9 and 2.0.0.1, and SeaMonkey before 1.0.8

Impact

By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user.

Recommended Actions

Firefox has addressed this issue in Firefox version 2.0.0.2 as well as Firefox 1.5.0.10. See Mozilla Foundation Security Advisory 2007-08 for more information
