You can find the 11.0 Collaboration SRND as well as previous versions of the SRND at the SRND landing page:  http://www.cisco.com/go/ucsrnd

While updates to SRND content were made throughout the document, the following are some notable highlights:

·         Gateways chapter: New sections on Expressway Business to Business Communications and Cisco Unified Border Elements

·         Collaboration Endpoints and Mobile Collaboration chapters: Coverage for Cisco Spark and the Cisco Collaboration Cloud.

·         Cisco Rich Media Conferencing chapter: Extensive updates made throughout including incorporation of applicable content from the previous Cisco Collaboration Services chapter.

·         Bandwidth Management chapter: New chapter replacing the previous Call Admission Control chapter.  In addition to the previous Call Admission Control content, this chapter has been updated extensively to cover QoS and other bandwidth management considerations.

·         Emergency Service chapter: Updated to include coverage for Unified CM native emergency call routing.

·         Collaboration Instant Messaging and Presence: Extensive updates made throughout including incorporation of some content from the previous Cisco Collaboration Clients chapter.

·         Cisco Collaboration Clients and Cisco Collaboration Services chapters: Eliminated with pertinent content moved to Collaboration Endpoints, Rich Media Conferencing, and Collaboration Instant Messaging and Presence chapters.

The Heartbleed Bug

heartbleed

The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).

The Heartbleed 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 on communications, steal data directly from the services and users and to impersonate services and users.

OpenSSL Heartbeat Extension Vulnerability in Multiple Cisco Products

Multiple Cisco products incorporate a version of the OpenSSL package affected by a vulnerability that could allow an unauthenticated, remote attacker to retrieve memory in chunks of 64 kilobytes from a connected client or server.

The vulnerability is due to a missing bounds check in the handling of the Transport Layer Security (TLS) heartbeat extension. An attacker could exploit this vulnerability by implementing a malicious TLS or Datagram Transport Layer Security (DTLS) client, if trying to exploit the vulnerability on an affected server, or a malicious TLS or DTLS server, if trying to exploit the vulnerability on an affected client. An exploit could send a specially crafted TLS or DTLS heartbeat packet to the connected client or server. An exploit could allow the attacker to disclose a limited portion of memory from a connected client or server for every heartbeat packet sent. The disclosed portions of memory could contain sensitive information that may include private keys and passwords.

Please note that the devices that are affected by this vulnerability are the devices acting as an SSL server terminating SSL connections or devices acting as an SSL Client initiating an SSL connection. Devices that are simply traversed by SSL traffic without terminating it are not affected.

This advisory will be updated as additional information becomes available. Cisco will release free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities may be available. This advisory is available at the following link:
