+ <background>
+ <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 "&gt;=www-client/opera-9.02"</code>
+ </resolution>
