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).

</description>
<impact type="normal">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time for all these
vulnerabilities.
</p>
</workaround>
<resolution>
<p>
All Opera users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/opera-9.24&quot;</code>
</resolution>
