<title>OpenSSL: SSL 2.0 protocol rollback</title>
|
|

|
|

OpenSSL is a toolkit implementing the Secure Sockets Layer, Transport
|
|
Layer Security protocols and a general-purpose cryptography library.

<p>
|
|
Applications setting the SSL_OP_MSIE_SSLV2_RSA_PADDING option (or the
|
|
SSL_OP_ALL option, that implies it) can be forced by a third-party to
|
|
fallback to the less secure SSL 2.0 protocol, even if both parties
|
|
support the more secure SSL 3.0 or TLS 1.0 protocols.

<impact type="low">
|
|
<p>
|
|
A man-in-the-middle attacker can weaken the encryption used to
|
|
communicate between two parties, potentially revealing sensitive
|
|
information.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
If possible, disable the use of SSL 2.0 in all OpenSSL-enabled
|
|
applications.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All OpenSSL users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose dev-libs/openssl</code>
|
|
