Security Bulletin: Vulnerabilities in OpenSSL including Logjam affect IBM® SDK for Node.js™ in IBM Bluemix

Security Bulletin


Summary

OpenSSL vulnerabilities were disclosed on June 11, 2015 by the OpenSSL Project. This includes the Logjam Attack on TLS connections using the Diffie-Hellman (DH) key exchange protocol (CVE-2015-4000) which affects IBM SDK for Node.js in IBM Bluemix.

Vulnerability Details

CVEID: CVE-2015-4000
DESCRIPTION:
 The TLS protocol could allow a remote attacker to obtain sensitive information, caused by the failure to properly convey a DHE_EXPORT ciphersuite choice. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to 512-bit export-grade cipher. Successful exploitation could allow an attacker to recover the session key as well as modify the contents of the traffic. This vulnerability is commonly referred to as "Logjam".
CVSS Base Score: 4.3

CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

CVEID: CVE-2014-8176
DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code on the system, caused by an invalid free error when application data between the ChangeCipherSpec and Finished messages is received by the DTLS peer. An attacker could exploit this vulnerability to trigger a segmentation fault or possibly corrupt memory and execute arbitrary

CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:P/A:P)

CVEID: CVE-2015-1788
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error when processing an ECParameters structure over a specially crafted binary polynomial field. A remote attacker could exploit this vulnerability to cause the application to enter into an infinite loop.
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/103778 for the current score

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-1789
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read in X509_cmp_time. An attacker could exploit this vulnerability using a specially crafted certificate or CRL to trigger a segmentation fault.
CVSS Base Score: 5

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-1790
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the improper handling of missing inner EncryptedContent by the PKCS#7 parsing code. An attacker could exploit this vulnerability using specially crafted ASN.1-encoded PKCS#7 blobs with missing content to trigger a NULL pointer dereference.

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-1791
DESCRIPTION: A double-free memory error in OpenSSL in the ssl3_get_new_session_ticket() function has an unknown impact. By returning a specially crafted NewSessionTicket message, an attacker could cause the client to reuse a previous ticket resulting in a race condition.

CVEID: CVE-2015-1792
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error when verifying a signedData message. An attacker could exploit this vulnerability using an unknown hash function OID to cause the application to enter into an infinite loop.

Affected Products and Versions

This vulnerability affects all versions up to and including IBM SDK for Node.js v1.1.0.14 and v1.2.0.2. It also affects open-source version v0.10.38 and v0.12.4 of the Node.js runtime in IBM Bluemix. The issue has been resolved in IBM SDK for Node.js v1.1.0.15 and v1.2.0.3 with Node.js Buildpack Version: v2.2-20150630-1721.

To check which version of the Node.js runtime your Bluemix application is using, navigate to the "Files and Logs" for your application through the Bluemix UI. In the "logs" directory, check the "staging_task.log". You can also find this file through the command-line Cloud Foundry client by running "cf files <appname> logs/staging_task.log".

Look for the following lines:

-----> IBM SDK for Node.js Buildpack _______

If the open-source version is not v0.10.39 or v0.12.5, or the buildpack verison is v2.2-xxxxxxxx-xxxx, your application may be vulnerable.

Remediation/Fixes

To upgrade to the latest version of the Node.js runtime, please specify the latest Node.js runtime in your package.json file for your application:

"engines": {
"node": ">=0.10.39"
},
or
"engines": {
"node": ">=0.12.5"
},

You will then need to restage (or re-push) your application.
