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>
|
|
The Google Security Team reported that several functions incorrectly
|
|
check the result after calling the EVP_VerifyFinal() function, allowing
|
|
a malformed signature to be treated as a good signature rather than as
|
|
an error. This issue affects the signature checks on DSA and ECDSA keys
|
|
used with SSL/TLS.

<impact type="normal">
|
|
<p>
|
|
A remote attacker could exploit this vulnerability and spoof arbitrary
|
|
names to conduct Man-In-The-Middle attacks and intercept sensitive
|
|
information.
|
|
</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-0.9.8j"</code>
