Arista 7000 Series Products and Arista EOS Not Vulnerable to OpenSSL CVE-2014-0160

On April 7th, the OpenSSL Project issued a security advisory for a TLS heartbeat read overrun vulnerability. This vulnerability allows attackers to access the memory of web servers and potentially access confidential data.

A number of customers have contacted Arista Networks, understandably worried that their Arista products are susceptible to the SSL vulnerability. We can confirm that Arista EOS and Arista 7000 Series products are not vulnerable.

This exploit was introduced with the implementation of RFC 6520 on more recent versions of OpenSSL. The affected versions of OpenSSL are as follows:

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 1.0.0e is NOT vulnerable

OpenSSL 0.9.8 branch is NOT vulnerable

Arista EOS do not include vulnerable versions of OpenSSL and are therefore NOT impacted by this vulnerability.
