Security Bulletin
Summary
OpenSSL vulnerabilities were disclosed on September 22 and 26, 2016 by the
OpenSSL Project. OpenSSL is used by IBM SDK for Node.js. IBM SDK for Node.js
has addressed the applicable CVEs, plus three additional vulnerabilities
unrelated to the OpenSSL release.
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-2016-6303
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-2016-2178
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)
CVEID: CVE-2016-7099
DESCRIPTION: Node.js could allow a remote attacker to bypass security
restrictions, caused by the improper verification of the host name. By
sending a specially-crafted certificate containing wildcard characters,
a remote attacker could exploit this vulnerability to gain access to
the system.
CVSS Base Score: 6.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117538 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:L/A:N)
CVEID: CVE-2016-5325
DESCRIPTION: Node.js is vulnerable to HTTP response splitting attacks,
caused by improper validation of user-supplied input by the reason argument
in ServerResponse#writeHead() function. A remote attacker could exploit
this vulnerability to inject arbitrary HTTP headers and cause the server
to return a split response, once the URL is clicked. This would allow
the attacker to perform further attacks, such as Web cache poisoning or
cross-site scripting, and possibly obtain sensitive information.
CVSS Base Score: 6.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117539 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)
DESCRIPTION: Node.js could allow a local attacker to execute arbitrary
code on the system, caused by the loading of third-party engine modules
when the ENGINE_load_builtin_engines() function is used. By impersonating
malicious code as a module, an attacker could exploit this vulnerability
to execute arbitrary code on the system.
CVSS Base Score: 4.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117537 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)
