Opera contains multiple vulnerabilities, which may allow the execution of
arbitrary code.

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