Multiple vulnerabilities have been discovered in Opera:
|
|
</p>
|
|
<ul>
|
|
<li>Opera does not restrict the ability of a framed web page to change
|
|
the address associated with a different frame (CVE-2008-4195).</li>
|
|
<li>Chris Weber (Casaba Security) discovered a Cross-site scripting
|
|
vulnerability (CVE-2008-4196).</li>
|
|
<li>Michael A. Puls II discovered
|
|
that Opera can produce argument strings that contain uninitialized
|
|
memory, when processing custom shortcut and menu commands
|
|
(CVE-2008-4197).</li>
|
|
<li>Lars Kleinschmidt discovered that Opera, when
|
|
rendering an HTTP page that has loaded an HTTPS page into a frame,
|
|
displays a padlock icon and offers a security information dialog
|
|
reporting a secure connection (CVE-2008-4198).</li>
|
|
<li>Opera does not
|
|
prevent use of links from web pages to feed source files on the local
|
|
disk (CVE-2008-4199).</li>
|
|
<li>Opera does not ensure that the address
|
|
field of a news feed represents the feed's actual URL
|
|
(CVE-2008-4200).</li>
|
|
<li>Opera does not check the CRL override upon
|
|
encountering a certificate that lacks a CRL (CVE-2008-4292).</li>
|
|
<li>Chris (Matasano Security) reported that Opera may crash if it is
|
|
redirected by a malicious page to a specially crafted address
|
|
(CVE-2008-4694).</li>
|
|
<li>Nate McFeters reported that Opera runs Java
|
|
applets in the context of the local machine, if that applet has been
|
|
cached and a page can predict the cache path for that applet and load
|
|
it from the cache (CVE-2008-4695).</li>
|
|
<li>Roberto Suggi Liverani
|
|
(Security-Assessment.com) reported that Opera's History Search results
|
|
does not escape certain constructs correctly, allowing for the
|
|
injection of scripts into the page (CVE-2008-4696).</li>
|
|
<li>David
|
|
Bloom reported that Opera's Fast Forward feature incorrectly executes
|
|
scripts from a page held in a frame in the outermost page instead of
|
|
the page the JavaScript URL was located (CVE-2008-4697).</li>
|
|
<li>David
|
|
Bloom reported that Opera does not block some scripts when previewing a
|
|
news feed (CVE-2008-4698).</li>
|
|
<li>Opera does not correctly sanitize
|
|
content when certain parameters are passed to Opera's History Search,
|
|
allowing scripts to be injected into the History Search results page
|
|
(CVE-2008-4794).</li>
|
|
<li>Opera's links panel incorrectly causes
|
|
scripts from a page held in a frame to be executed in the outermost
|
|
page instead of the page where the URL was located
|
|
(CVE-2008-4795).</li>
|
|
</ul>

<impact type="normal">
|
|
<p>
|
|
These vulnerabilties allow remote attackers to execute arbitrary code,
|
|
to run scripts injected into Opera's History Search with elevated
|
|
privileges, to inject arbitrary web script or HTML into web pages, to
|
|
manipulate the address bar, to change Opera's preferences, to determine
|
|
the validity of local filenames, to read cache files, browsing history,
|
|
and subscribed feeds or to conduct other attacks.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Opera users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-client/opera-9.62"</code>
|
|
</resolution>
