CVE-2013-0169
Description
From CVE.org
The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, aka the "Lucky Thirteen" issue.
Mitigation
On OpenShift Container Platform 3.11 it's possible to edit the list of cipher suites offered by the router when performing 'edge', or 're-encrypt' TLS modes. Please follow the documentation [1], and [2] to remove the vulnerable CBC ciphers use the modern, or intermediate cipher suites outlined by Mozilla instead [3]. In 'passthrough' mode TLS termination occurs in the application so that is another way to mitigate the vulnerability.

Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
CVSS v2 Score Breakdown
