<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 ">=www-client/opera-9.02"</code>
