iDefense Security Advisory 05.23.07 – Remote exploitation of a stack-based buffer overflow in Opera Software ASA’s Opera Web browser could allow an attacker to execute arbitrary code on the affected host. Opera 9.2 supports BitTorrent downloads. If a server sends the browser a specially crafted BitTorrent header, it can lead to a buffer overflow. The buffer overflow is triggered when the user right clicks on the item in the download pane. iDefense has confirmed the existence of this vulnerability in the Opera version 9.2 for Windows. Previous versions may also be affected.
