Mozilla Foundation Security Advisory 2009-35
Title: Crash and remote code execution during Flash player unloading
Impact: Critical
Announced: July 21, 2009
Reporter: Attila Suszter
Products: Firefox
Fixed in: Firefox 3.5.1
Firefox 3.0.12
Description
Security researcher Attila Suszter reported that when a page contains a Flash object which presents a slow script dialog, and the page is navigated while the dialog is still visible to the user, the Flash plugin is unloaded resulting in a crash due to a call to the deleted object. This crash could potentially be used by an attacker to run arbitrary code on a victim's computer.
