(OpenSSL: Multiple vulnerabilities)

    Multiple vulnerabilities have been reported in OpenSSL:
    Marsh Ray of PhoneFactor and Martin Rex of SAP independently
    reported that the TLS protocol does not properly handle session
    renegotiation requests (CVE-2009-3555).
    The MD2 hash algorithm is no longer considered to be
    cryptographically strong, as demonstrated by Dan Kaminsky. Certificates
    using this algorithm are no longer accepted (CVE-2009-2409).
    Daniel Mentz and Robin Seggelmann reported the following
    vulnerabilities related to DTLS: A use-after-free flaw (CVE-2009-1379)
    and a NULL pointer dereference (CVE-2009-1387) in the
    dtls1_retrieve_buffered_fragment() function in src/d1_both.c, multiple
    memory leaks in the dtls1_process_out_of_seq_message() function in
    src/d1_both.c (CVE-2009-1378), and a processing error related to a
    large amount of DTLS records with a future epoch in the
    dtls1_buffer_record() function in ssl/d1_pkt.c
    (CVE-2009-1377).
  
Impact :

    A remote unauthenticated attacker, acting as a Man in the Middle, could
    inject arbitrary plain text into a TLS session, possibly leading to the
    ability to send requests as if authenticated as the victim. A remote
    attacker could furthermore send specially crafted DTLS packages to a
    service using OpenSSL for DTLS support, possibly resulting in a Denial
    of Service. Also, a remote attacker might be able to create rogue
    certificates, facilitated by a MD2 collision. NOTE: The amount of
    computation needed for this attack is still very large.
  
Workaround :

    There is no known workaround at this time."
