  <title>OpenSSL: Remote execution of arbitrary code</title>
  <synopsis>
    OpenSSL contains a vulnerability allowing execution of arbitrary code or a
    Denial of Service.

    <package name="dev-libs/openssl" auto="yes" arch="*">

  <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>
    Andy Polyakov reported a vulnerability in the OpenSSL toolkit, that is
    caused due to an unspecified off-by-one error within the DTLS
    implementation.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could exploit this issue to execute arbitrary code or
    cause a Denial of Service. Only clients and servers explicitly using
    DTLS are affected, systems using SSL and TLS are not.
    </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-0.9.8f"</code>
  </resolution>
