    Multiple vulnerabilities have been found in OpenSSL. Please review the
      CVE identifiers and the upstream advisory referenced below for details:
      RSA silently downgrades to EXPORT_RSA [Client] (Reclassified)
        (CVE-2015-0204)
      Segmentation fault in ASN1_TYPE_cmp (CVE-2015-0286)
      ASN.1 structure reuse memory corruption (CVE-2015-0287)
      X509_to_X509_REQ NULL pointer deref (CVE-2015-0288)
      PKCS7 NULL pointer dereferences (CVE-2015-0289)
      Base64 decode (CVE-2015-0292)
      DoS via reachable assert in SSLv2 servers (CVE-2015-0293)
      Use After Free following d2i_ECPrivatekey error (CVE-2015-0209)
    The following issues affect OpenSSL 1.0.2 only which is not part of the
      supported Gentoo stable tree:
      OpenSSL 1.0.2 ClientHello sigalgs DoS (CVE-2015-0291)
      Multiblock corrupted pointer (CVE-2015-0290)
      Segmentation fault in DTLSv1_listen (CVE-2015-0207)
      Segmentation fault for invalid PSS parameters (CVE-2015-0208)
      Empty CKE with client auth and DHE (CVE-2015-1787)
      Handshake with unseeded PRNG (CVE-2015-0285)
  
Impact :

    A remote attacker can utilize multiple vectors to cause Denial of
      Service or Information Disclosure.
  
Workaround :

    There is no known workaround at this time."
