+ An error in the OpenSSL certificate chain validation might allow for
+ spoofing attacks.

+ <background>
+ <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.
+ </p>
+ </background>
+ <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.
+ </p>
+ </description>
+ <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 "&gt;=dev-libs/openssl-0.9.8j"</code>
