Synopsis :

An enterprise management application installed on the remote host is
affected by multiple vulnerabilities.

Description :

The version of Oracle Enterprise Manager Grid Control installed on
the remote host is missing a security patch. It is, therefore,
affected by multiple vulnerabilities :

- Multiple integer overflow conditions exist in the
OpenSSL component in s3_srvr.c, ssl_sess.c, and t1_lib.c
due to improper use of pointer arithmetic for
heap-buffer boundary checks. An unauthenticated, remote
attacker can exploit this to cause a denial of service
condition. (CVE-2016-2177)

- An information disclosure vulnerability exists in the
OpenSSL component in dsa_sign_setup() function in
dsa_ossl.c due to a failure to properly ensure the use
of constant-time operations. An unauthenticated, remote
attacker can exploit this, via a timing side-channel
attack, to disclose DSA key information. (CVE-2016-2178)

- A denial of service vulnerability exists in the OpenSSL
component in the DTLS implementation due to a failure to
properly restrict the lifetime of queue entries
associated with unused out-of-order messages. An
unauthenticated, remote attacker can exploit this, by
maintaining multiple crafted DTLS sessions
simultaneously, to exhaust memory. (CVE-2016-2179)

- An out-of-bounds read error exists in the OpenSSL
component in the X.509 Public Key Infrastructure
Time-Stamp Protocol (TSP) implementation. An
unauthenticated, remote attacker can exploit this, via a
crafted time-stamp file that is mishandled by the
'openssl ts' command, to cause denial of service or to
disclose sensitive information. (CVE-2016-2180)

- A denial of service vulnerability exists in the OpenSSL
component in the Anti-Replay feature in the DTLS
implementation due to improper handling of epoch
sequence numbers in records. An unauthenticated, remote
attacker can exploit this, via spoofed DTLS records, to
cause legitimate packets to be dropped. (CVE-2016-2181)

- An overflow condition exists in the OpenSSL component in
the BN_bn2dec() function in bn_print.c due to improper
validation of user-supplied input when handling BIGNUM
values. An unauthenticated, remote attacker can exploit
this to crash the process. (CVE-2016-2182)

- A vulnerability exists in the OpenSSL component, known
as SWEET32, in the 3DES and Blowfish algorithms due to
the use of weak 64-bit block ciphers by default. A
man-in-the-middle attacker who has sufficient resources
can exploit this vulnerability, via a 'birthday' attack,
to detect a collision that leaks the XOR between the
fixed secret and a known plaintext, allowing the
disclosure of the secret text, such as secure HTTPS
cookies, and possibly resulting in the hijacking of an
authenticated session. (CVE-2016-2183)

- A denial of service vulnerability exists in the Apache
Commons FileUpload component due to improper handling of
boundaries in content-type headers when handling file
upload requests. An unauthenticated, remote attacker can
exploit this to cause processes linked against the
library to become unresponsive. (CVE-2016-3092)

- A flaw exists in the OpenSSL component in the
tls_decrypt_ticket() function in t1_lib.c due to
improper handling of ticket HMAC digests. An
unauthenticated, remote attacker can exploit this, via a
ticket that is too short, to crash the process,
resulting in a denial of service. (CVE-2016-6302)

- An integer overflow condition exists in the OpenSSL
component in the MDC2_Update() function in mdc2dgst.c
due to improper validation of user-supplied input. An
unauthenticated, remote attacker can exploit this to
cause a heap-based buffer overflow, resulting in a
denial of service condition or possibly the execution of
arbitrary code. (CVE-2016-6303)

- A flaw exists in the OpenSSL component in the
ssl_parse_clienthello_tlsext() function in t1_lib.c due
to improper handling of overly large OCSP Status Request
extensions from clients. An unauthenticated, remote
attacker can exploit this, via large OCSP Status Request
extensions, to exhaust memory resources, resulting in a
denial of service condition. (CVE-2016-6304)

- A flaw exists in the OpenSSL component in the SSL_peek()
function in rec_layer_s3.c due to improper handling of
empty records. An unauthenticated, remote attacker can
exploit this, by triggering a zero-length record in an
SSL_peek call, to cause an infinite loop, resulting in a
denial of service condition. (CVE-2016-6305)

- An out-of-bounds read error exists in the OpenSSL
component in the certificate parser that allows an
unauthenticated, remote attacker to cause a denial of
service via crafted certificate operations.
(CVE-2016-6306)

- A denial of service vulnerability exists in the OpenSSL
component in the state-machine implementation due to a
failure to check for an excessive length before
allocating memory. An unauthenticated, remote attacker
can exploit this, via a crafted TLS message, to exhaust
memory resources. (CVE-2016-6307)

- A denial of service vulnerability exists in the OpenSSL
component in the DTLS implementation due to improper
handling of excessively long DTLS messages. An
unauthenticated, remote attacker can exploit this, via a
crafted DTLS message, to exhaust available memory
resources. (CVE-2016-6308)

- A remote code execution vulnerability exists in the
OpenSSL component in the read_state_machine() function
in statem.c due to improper handling of messages larger
than 16k. An unauthenticated, remote attacker can
exploit this, via a specially crafted message, to cause
a use-after-free error, resulting in a denial of service
condition or possibly the execution of arbitrary code.
(CVE-2016-6309)

- A denial of service vulnerability exists in the OpenSSL
component in x509_vfy.c due to improper handling of
certificate revocation lists (CRLs). An unauthenticated,
remote attacker can exploit this, via a specially
crafted CRL, to cause a NULL pointer dereference,
resulting in a crash of the service condition.
(CVE-2016-7052)

- An unspecified flaw exists in the Discovery Framework
subcomponent that allows an unauthenticated, remote
attacker to cause a denial of service condition.
(CVE-2017-3518)
