the OpenSSL Project. OpenSSL is used by IBM Cognos Metrics Manager. IBM
Cognos Metrics Manager has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2016-6302
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
failure to consider the HMAC size during validation of the ticket length
by the tls_decrypt_ticket function A remote attacker could exploit this
vulnerability using a ticket that is too short to cause a denial of service.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117024 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-6304
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by multiple
memory leaks in t1_lib.c during session renegotiation. By sending an overly
large OCSP Status Request extension, a remote attacker could exploit this
vulnerability to consume all available memory resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117110 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2016-6303
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an
integer overflow in the MDC2_Update function. By using unknown attack
vectors, a remote attacker could exploit this vulnerability to trigger an
out-of-bounds write and cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117023 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-2177
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
incorrect use of pointer arithmetic for heap-buffer boundary checks. By
leveraging unexpected malloc behavior, a remote attacker could exploit
this vulnerability to trigger an integer overflow and cause the application
to crash.
CVSS Base Score: 5.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/113890 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2016-2178
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error in the DSA implementation that allows
the following of a non-constant time codepath for certain operations. An
attacker could exploit this vulnerability using a cache-timing attack to
recover the private DSA key.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/113889 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2016-2179
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending
specially crafted DTLS record fragments to fill up buffer queues, a
remote attacker could exploit this vulnerability to open a large number
of simultaneous connections and consume all available memory resources.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/116343 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-6306
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by missing
message length checks when parsing certificates. A remote authenticated
attacker could exploit this vulnerability to trigger an out-of-bounds read
and cause a denial of service.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117112 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-2181
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an
error in the DTLS replay protection implementation. By sending a specially
crafted sequence number, a remote attacker could exploit this vulnerability
to cause valid packets to be dropped.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/116344 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-2183
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error in the DES/3DES cipher, used as a part of the
SSL/TLS protocol. By capturing large amounts of encrypted traffic between
the SSL/TLS server and the client, a remote attacker able to conduct a
man-in-the-middle attack could exploit this vulnerability to recover the
plaintext data and obtain sensitive information. This vulnerability is
known as the SWEET32 Birthday attack.
CVSS Base Score: 3.7
CVSS Temporal Score: See
