An anonymous reader writes "Security researchers at Foreground Security have found an issue with Adobe Flash. Any site that allows files to be uploaded could be vulnerable to this issue (whether they serve Flash or not!). Adobe has said that no easy fix exists and no patch is forthcoming. Adobe puts the responsibility on the website administrators themselves to fix this problem, but they themselves seem to be vulnerable to these problems. Every user with Flash installed is vulnerable to this new type of attack and — until IT administrators fix their sites — will continue to be."
