Synopsis
========

Opera is vulnerable to several vulnerabilities which could result in
information disclosure and facilitate execution of arbitrary code.

Background
==========

Opera is a multi-platform web browser.

Affected packages
=================

    -------------------------------------------------------------------
     Package        /  Vulnerable  /                        Unaffected
    -------------------------------------------------------------------
  1  net-www/opera      < 7.54-r3                           >= 7.54-r3

Description
===========

Opera contains several vulnerabilities:

* fails to properly validate Content-Type and filename.

* fails to properly validate date: URIs.

* uses kfmclient exec as the Default Application to handle downloaded
  files when integrated with KDE.

* fails to properly control frames.

* uses Sun Java packages insecurely.

* searches an insecure path for plugins.

Impact
======

An attacker could exploit these vulnerabilities to:

* execute arbitrary code.

* load a malicious frame in the context of another browser session.

* leak information.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Opera users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-www/opera-7.54-r3"
