You wish to know if the Symantec Mail Security for Microsoft Exchange (SMSMSE) is affected by the "heartbleed" OpenSSL bug (CVE-2014-0160) that allows highly sensitive material such as primary key information to be accessed illicitly via a defect in the implementation of the TLS/DTLS (transport layer security protocols) heartbeat extension (RFC6520).
The SMSMSE isNOT AFFECTED by this vulnerability, as it does not use the TLS / DTLS functionality from OpenSSL. However, anoptionalpatch is offered, simply to exclude the specific OpenSSL version (1.0.1e) from the build. This patch is built with OpenSSL 1.0.1g.
This proactive patch is purely OPTIONAL. SMSMSE 220.127.116.11 isNOT AFFECTED by the HeartBleed vulnerabilitywithout this patch.
