Discussion
On April 7 2014, US-CERT issued advisory 720951.
(This issue is also tracked as CVE-2014-0160, and discussed in 16130.)

The advisory overview...
OpenSSL 1.0.1 contains a vulnerability that could disclose sensitive private information to an attacker. This vulnerability is commonly referred to as "heartbleed."

The advisory impact...
By attacking a service that uses a vulnerable version of OpenSSL, a remote, unauthenticated attacker may be able to retrieve sensitive information, such as secret keys. By leveraging this information, an attacker may be able to decrypt, spoof, or perform man-in-the-middle attacks on network traffic that would otherwise be protected by OpenSSL.

The advisory lists a number of affected vendors, including Extreme Networks and Enterasys Networks.

If within the advisory the hyperlinked Extreme Networks or Enterasys Networks Information still reads "No statement is currently available from the vendor regarding this vulnerability.", then please refer to this statement (.pdf, 200 KB) submitted to US-CERT on April 11 2014.

EXOS 15.4.1-patch1-10 is available for download via eSupport's "Download Software Updates" link.
The NetSight patch is available for download from the NMS Product page, or here (1.5 MB).
A set of Dragon signatures was released on April 9, to assist in detecting attempted exploits.
