FreeBSD : OpenSSL -- Remote Information Disclosure (5631ae98-be9e-11e3-b5e3-c80aa9043978)

high Nessus Plugin ID 73389
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

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.

Solution

Update the affected packages.
