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.",

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. TLS configuration options for OCP are described here:\n\nhttps://access.redhat.com/articles/5348961",
