<p>
Opera is a multi-platform web browser.

<description>
<p>
Opera makes use of OpenSSL, which fails to correctly verify PKCS #1
v1.5 RSA signatures signed by a key with exponent 3. Some CAs in
Opera's list of trusted signers are using root certificates with
exponent 3.
</p>
</description>
<impact type="normal">
<p>
An attacker could forge certificates which will appear valid and signed
by a trusted CA.
</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 &quot;&gt;=www-client/opera-9.02&quot;</code>
</resolution>
