<p>OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer
|
|
(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general
|
|
purpose cryptography library.

<description>
|
|
<p>During certificate verification, OpenSSL attempts to find an alternative
|
|
certificate chain if the first attempt to build such a chain fails.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>A remote attacker could cause certain checks on untrusted
|
|
certificates to be bypassed, such as the CA flag, enabling them to use a
|
|
valid leaf certificate to act as a CA and “issue” an invalid
|
|
certificate.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All OpenSSL users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.1p"
|
|
</code>
