Does F5 use any of the vulnerable versions of openSSL?

 

Status of different versions:

 

OpenSSL 1.0.1 through 1.0.1f (inclusive) are vulnerable OpenSSL 1.0.1g is NOT vulnerable OpenSSL 1.0.0 branch is NOT vulnerable OpenSSL 0.9.8 branch is NOT vulnerable

  • Virtual servers using an SSL profile configured with the default Native SSL ciphers are not vulnerable. Only virtual servers using an SSL profile configured to use ciphers from the COMPAT SSL stack are vulnerable in BIG-IP 11.5.0 and 11.5.1. In addition, virtual servers that do not use SSL profiles and pass SSL traffic to the back-end web servers will not protect the back-end resource servers.
