Security Bulletin
Summary
SSL vulnerabilities were disclosed on September 22 and 26, 2016 by the OpenSSL
Project. IBM DataPower Gateways has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2016-6304
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By repeatedly
requesting renegotiation, a remote authenticated attacker could send an overly
large OCSP Status Request extension to consume all available memory resources.
CVSS Base Score: 6.5
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-2016-2182
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an
out-of-bounds write in the TS_OBJ_print_bio function in crypto/bn/bn_print.c.
A remote attacker could exploit this vulnerability using a specially crafted
value to cause the application to crash.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/116342 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/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-2016-6306
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-2016-2183
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by an error in the in the Triple-DES on 64-bit block
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
https://exchange.xforce.ibmcloud.com/vulnerabilities/116337 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
