Opera Software Opera Web Browser Transfer Item Pop-up Menu Stack Overflow
Vulnerability
------------------------------------------------------------------------


SUMMARY

<http://www.opera.com/> Opera is "a cross-platform web browser". 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.

DETAILS

Vulnerable Systems:
* Opera version 9.2 for Windows.
* Previous versions may also be affected.

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.

Exploitation of this vulnerability allows an attacker to execute arbitrary
code on the affected host.

The attacker must convince the vulnerable user into clicking a link to a
BitTorrent file.
