Summary
Red Hat Security Advisory: OpenShift Container Platform 4.1.18 security update
Notes
Topic
An update for golang-github-openshift-oauth-proxy-container is now available for Red Hat OpenShift Container Platform 4.1.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat OpenShift Container Platform is Red Hat's cloud computing
Kubernetes application platform solution designed for on-premise or private
cloud deployments.
Security Fix(es):
* A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite. (CVE-2016-2183)

For compatibility reasons, DES cipher suites remain enabled by default and included in the set of cipher suites identified by the HIGH cipher string. Future updates may move them to MEDIUM or not enable them by default.\n\nNSS addressed this issue by implementing limits on the amount of plain text which can be encrypted by using the same key. Once the limit is reached, the keys will need to be re-negotiated manually. This change will be available in nss-3.27.\n\nGnuTLS is not affected by this issue, since it prioritizes AES before 3DES in the cipher list.",

"details": "1.SSL/TLS configurations should prefer AES over DES. Versions of OpenSSL shipped with Red Hat Enterprise Linux 6 and 7 already do so. In the version of OpenSSL shipped with Red Hat Enterprise Linux 5, 3DES is listed below the AES-256 cipher and above the AES-128 cipher, therefore AES-256 based ciphersuite should not be disabled on the server.\n2. Servers using OpenSSL, should not disable AES-128 and AES-256 ciphersuites. Versions of Apache shipped with Red Hat Enterprise Linux use the default cipher string, in which AES is preferred over DES/3DES based ciphersuites.\n\nFor JBoss Middleware, and Java mitigations, please review this knowledge base article:\n\nhttps://access.redhat.com/articles/2598471\n\nThis can be mitigated on OpenShift Container Platform (OCP) by disabling the vulnerable TLS cipher suite in the applicable component.
