Opera < 9.22 Multiple Vulnerabilities

high Nessus Plugin ID 25755

Synopsis

The remote host contains a web browser that is affected by multiple issues.

Description

The version of Opera installed on the remote host reportedly can be tricked into attempting to dereference an invalid object pointer when parsing a specially crafted BitTorrent header. This could cause the application to crash or even lead to execution of arbitrary code subject to the privileges of the current user.

Successful exploitation requires that a user on the affected host click on a link to a BitTorrent file and then remove the entry from Opera's download manager.

In addition, it can mistakenly display the end of a 'data:' URL rather than the beginning, which can lead to spoofing of trusted sites.

Solution

Upgrade to Opera version 9.22 or later.
