"OpenSSL Reports :

A missing bounds check in the handling of the TLS heartbeat extension
can be used to reveal up to 64k of memory to a connected client or
server.

Affected users should upgrade to OpenSSL 1.0.1g. Users unable to
immediately upgrade can alternatively recompile OpenSSL with
-DOPENSSL_NO_HEARTBEATS.

The bug allows anyone on the Internet to read the memory of the
systems protected by the vulnerable versions of the OpenSSL software.
This compromises the secret keys used to identify the service
providers and to encrypt the traffic, the names and passwords of the
users and the actual content. This allows attackers to eavesdrop
communications, steal data directly from the services and users and to
impersonate services and users.

The code used to handle the Heartbeat Extension does not do sufficient
boundary checks on record length, which allows reading beyond the
actual payload.");
