    The OpenSSL toolkit provides support for secure communications between
    machines. OpenSSL includes a certificate management tool and shared
    libraries which provide various cryptographic algorithms and
    protocols.
    Security issues fixed with this release:
    CVE-2016-2177
    OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for
    heap-buffer boundary checks, which might allow remote attackers to
    cause a denial of service (integer overflow and application crash) or
    possibly have unspecified other impact by leveraging unexpected malloc
    behavior, related to s3_srvr.c, ssl_sess.c, and t1_lib.c.
    CVE-2016-2178
    The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL
    through 1.0.2h does not properly ensure the use of constant-time
    operations, which makes it easier for local users to discover a DSA
    private key via a timing side-channel attack.
    CVE-2016-2179
    The DTLS implementation in OpenSSL before 1.1.0 does not properly
    restrict the lifetime of queue entries associated with unused
    out-of-order messages, which allows remote attackers to cause a denial
    of service (memory consumption) by maintaining many crafted DTLS
    sessions simultaneously, related to d1_lib.c, statem_dtls.c,
    statem_lib.c, and statem_srvr.c.
    CVE-2016-2180
    The TS_OBJ_print_bio function in crypto/ts/ts_lib.c in the X.509
    Public Key Infrastructure Time-Stamp Protocol (TSP) implementation in
    OpenSSL through 1.0.2h allows remote attackers to cause a denial of
    service (out-of-bounds read and application crash) via a crafted
    time-stamp file that is mishandled by the openssl ts command.
    CVE-2016-2181
    The Anti-Replay feature in the DTLS implementation in OpenSSL before
    1.1.0 mishandles early use of a new epoch number in conjunction with a
    large sequence number, which allows remote attackers to cause a denial
    of service (false-positive packet drops) via spoofed DTLS records,
    related to rec_layer_d1.c and ssl3_record.c.
    CVE-2016-2182
    The BN_bn2dec function in crypto/bn/bn_print.c in OpenSSL before 1.1.0
    does not properly validate division results, which allows remote
    attackers to cause a denial of service (out-of-bounds write and
    application crash) or possibly have unspecified other impact via
    unknown vectors.
    CVE-2016-6302
    The tls_decrypt_ticket function in ssl/t1_lib.c in OpenSSL before
    1.1.0 does not consider the HMAC size during validation of the ticket
    length, which allows remote attackers to cause a denial of service via
    a ticket that is too short.
    CVE-2016-6304
    Multiple memory leaks in t1_lib.c in OpenSSL before 1.0.1u, 1.0.2
    before 1.0.2i, and 1.1.0 before 1.1.0a allow remote attackers to cause
    a denial of service (memory consumption) via large OCSP Status Request
    extensions.
    CVE-2016-6306
    The certificate parser in OpenSSL before 1.0.1u and 1.0.2 before
    1.0.2i might allow remote attackers to cause a denial of service
    (out-of-bounds read) via crafted certificate operations, related to
    s3_clnt.c and s3_srvr.c.
