A 'highly critical' vulnerability has been found in the
Opera web
browser which could be exploited to remotely compromise a user's system.
The flaw is caused when Opera uses already freed memory to parse
BitTorrent
headers, and can lead to an invalid object pointer being de-referenced.
This can be exploited to execute arbitrary code if the user is tricked into
clicking on a specially-crafted BitTorrent file and then removes it from the
download pane by right-clicking.
The vulnerability is reported in version 9.21 of Opera on Windows, but
security monitoring website
Secunia, which
rated the flaw 'highly critical', said that other versions may also be
affected.
The problem can be fixed by upgrading to Opera 9.22.
