Synopsis
=======
Opera contains multiple vulnerabilities, which may allow the execution
of arbitrary code.
Background
=========
Opera is a multi-platform web browser.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/opera < 9.24 >= 9.24
Description
==========
Michael A. Puls II discovered an unspecified flaw when launching
external email or newsgroup clients (CVE-2007-5541). David Bloom
discovered that when displaying frames from different websites, the
same-origin policy is not correctly enforced (CVE-2007-5540).
Impact
=====
An attacker could potentially exploit the first vulnerability to
execute arbitrary code with the privileges of the user running Opera by
enticing a user to visit a specially crafted URL. Note that this
vulnerability requires an external e-mail or newsgroup client
configured in Opera to be exploitable. The second vulnerability allows
an attacker to execute arbitrary script code in a user's browser
session in context of other sites or the theft of browser credentials.
Workaround
=========
There is no known workaround at this time for all these
vulnerabilities.
Resolution
=========
All Opera users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/opera-9.24"
