About this release This document contains important information about the current release. We strongly recommend that you read the entire document. This maintenance release of Network Security Platform is to provide few enhancements and fixes on the Sensor software. Network Security Manager software version: 8.1.7.5 Signature Set: 8.6.28.4 M-series Sensor software version: 8.1.3.43 Network Security Platform version 8.1 replaces 8.0 release. If you are using version 8.0 and require any fixes, note that the fixes will be provided in version 8.1. There will not be any new maintenance releases or hot-fix releases on version 8.0. With release 8.1, Network Security Platform no longer supports the Network Access Control module and N-series Sensors. If you are using Network Access Control with N-series (NAC-only) Sensors, McAfee recommends that you continue to use the 7.1.3.6 version. If you are using the Network Access Control module in M-series Sensors, continue to use the 7.5.3.30 version. That is, you should not upgrade the Manager or the Sensors to 8.1 for such cases. Manager software version 7.5 and above are not supported on McAfee-built Dell based Manager Appliances. This version of 8.1 Manager software can be used to configure and manage the following hardware: 7.1, 7.5, and 8.1 M series and Mxx30-series Sensors 8.1 Virtual IPS Sensors 7.1 and 8.1 NS-series Sensors 7.1, 7.5, and 8.1 XC Cluster Appliances 7.1, 7.5, and 8.1 NTBA Appliance software (Physical and Virtual) 7.1 I-series Sensors Currently port 4167 is used as the UDP source port number for the SNMP command channel communication between Manager and Sensors. This is to prevent opening up all UDP ports for inbound connectivity from SNMP ports on the sensor. Older JRE versions allowed the Manager to bind to the same source port 4167 for both IPv4 and IPv6 communication. But with the latest JRE version 1.7.0_45, it is no longer possible to do so, and the Manager uses port 4166 as the UDP source port to bind for IPv6. Manager 8.1 uses JRE version 1.7.0_51. If you have IPv6 Sensors behind a firewall, you need to update your firewall rules accordingly such that port 4166 is open for the SNMP command channel to function between those IPv6 Sensors and the Manager. New features This release is to provide few bug fixes for some of the previously known Sensor software issues, and does not include any new feature. 2
Enhancements This release of Network Security Platform includes the following enhancements: L3/L4 error count enhancement Previously, the error count for L3/L4 errors in a SPAN port could not be viewed even when the errors sometimes crossed the specified threshold limit. With this maintenance release, a new counter, getl3l4errordropcount in the debug command show all datapath error-counters, provides the error count for the L3/L4 errors. SNMP OID enhancement With this release, certain system parameters like the free memory, cache memory and buffer memory are monitored. The following SNMP OIDs are supported with regard to system monitoring: Control Path System Free Memory 1.3.6.1.4.1.8962.2.1.3.1.4.1.1.1.1 Control Path System Cached Memory 1.3.6.1.4.1.8962.2.1.3.1.4.1.1.2.1 Control Path System Buffer Memory 1.3.6.1.4.1.8962.2.1.3.1.4.1.1.3.1 2048-bit certificates for encryption The Manager and Sensor have so far established trust using 1024-bit certificates. With the growing need for enhanced security, this connection is being upgraded to be encrypted using 2048-bit certificates. Network Security Platform 8.1 supports heterogeneous environments, which accommodate both 1024-bit and 2048-bit encryption. That is, the Manager is both 1024 and 2048-bit capable, and can be used to manage Sensors running on 2048-bit capable and/or 1024-bit capable software versions. Trust establishment after upgrade is discussed below for each instance: 1024-bit encryption When a Sensor with software that does not support 2048-bit encryption is loaded and the Manager is upgraded to a version that supports 2048-bit encryption, the Sensor can establish trust with the Manager using 1024-bit certificates. 2048-bit encryption Both the 8.1 Manager and Sensor software support trust establishment using 2048-bit encryption keys. During upgrade, once you have upgraded the Manager software to 8.1, the 7.x Sensors can continue to connect to the Manager by establishing trust using 1024-bit encryption. After the Sensor upgrade to 8.1 version is also complete, the Sensor will connect to the ports opened for 2048-bit encryption. Once the certificates are updated, the Sensor and Manager establish communication using 2048-bit certificates. The ports necessary for 2048-bit encryption are: Port Description 8506 Install channel (TCP) 8507 Alert channel (TCP) 8508 Packet log channel (TCP) The upgrade from 1024-bit to 2048-bit encryption is done automatically with no user intervention necessary. Once done, use the status command to view the encryption type, and show command to view the ports used for 2048-bit encryption. 3

For a list of issues fixed in earlier releases, see the Release Notes for the specific release. Resolved Manager software issues The following table lists the medium-severity Manager software issues: ID # Issue Description 964765 The Manager using Apache Struts is vulnerable to CVE-2014-0094. 964715 The Botnet DAT update fails on multiple Sensors. 962218 The effective time for Firewall and QoS policies is based on the local time zone of the corresponding Sensor. 960959 The SNMP server setting configuration is not displayed after saving due to incorrect redirection. 960656 SNMP alert notification fails sometimes due to incorrect calculation of the Manager uptime. 959996 The Manager sends wrong port speed value to the Sensor while configuring monitoring port with SFP +. 959807 Alert filter in the Real-Time Threat Analyzer shows alerts from unknown country, irrespective of the source and destination countries selected. 959410 The Manager raises an "INFO" alert for malicious files before the files are sent to ATD for analysis, and "HIGH" alert after the files are confirmed to be malicious by ATD. Both alerts are generated with an "Acknowledged" flag. The "Acknowledged" flag remains the same irrespective of the severity of the alert which makes it difficult to differentiate the alerts generated. 959221 The Real-Time Threat Analyzer shows an error for multicast host IPv4 addresses while creating a new exception object. 957285 The Protection Profile page stops responding when opened in Chrome browser and eventually leads to Java crashing. 956340 The Manager fault for exceeding the 10,000 AD user groups limit is displayed incorrectly in the Manager. 954516 The scheduled configuration backup cannot be restored completely due to inclusion of all the tables during backup. 953875 The password control settings displays the wrong error message "minimum number of Characters should be between 1 and 20". 952088 The Real-Time Threat Analyzer triggers attack by the host even after creating an exception object. 951549 The Manager's connection with XC-240 load balancer is not recovered if the link is down for more than 9 minutes. 950005 When "Layer 7" data is selected to be included in the Next Generation report for alert data, the report is generated for dates not included in the report schedule. 949576 Incorrect pop-up message is displayed when the SSL flow count entered is more than the maximum allowed limit. 949202 Scripts for alert notification does not execute if the attack-severity variable ($ATTACK_SEVERITY$) is used. 947428 The Fault Log report generates events for template Sensors of XC Cluster but no other Cluster members. 946781 The Chrome browser crashes when the Manager is opened in Windows 8.0 mode. The following table lists the low-severity Manager software issues: 4
ID # Issue Description 962714 Malware archive fault message is misleading. Resolved Sensor software issues The following table lists the medium-severity Sensor software issues: ID # Issue Description 1012154 In rare scenarios, the Sensor either goes to layer2 or reboots when new configuration updates are deployed to the Sensor. 1007014 When the Sensor experiences abnormal reboot, or in a failover configuration if one of the Sensor reboots, then the front end processor gets stuck in rare scenarios. 1005048 The SNMP Get/Walk executed on the Sensor returns the SCP file server credentials. 992436 Firewall policy does not block some HTTPS applications. 982750 In a rare case scenario, there is traffic delay shortly after a signature or configuration update to the Sensor. 981250 Filename is missing in Malware Details section of alert details for GTI and ATD. 979110 When quarantine is enabled in the connection limiting policy, the first quarantined host is not released after the specified release time. 978286 ARP packets (matching the MAC flip flop event) are dropped which leads to network outage in rare scenarios. This happens when MAC flip flop attack is disabled and Heuristic Web Application Server Protection(WASP) is enabled on any interface of the Sensor. 977449 After a Sensor name change, the $IV_SENSOR_NAME$ flag is not updated until Sensor reboot. 973547 In rare scenario, when SSL decryption is enabled, the show sensor-load displays incorrect value of Sensor load. 973385 In rare scenario, the Sensor reboots due to memory corruption in the malware detection process. 970872 When the PDF emulator engine is configured for malware detection, the Sensor reboots in certain scenarios. 969760 The GTI queries fail during DNS resolution when the Sensor processes CNAME instead of A record of the proxy server. 969563 Layer 7 data are missing for alerts generated by ATD. 968947 The Sensor throughput value is displayed as 9GB for 1GB ports in the Manager. 966281 In rare scenarios, routers running EIGRP experience neighbor adjacency flap while the Sensor processes the EIGRP update packets. 965633 In rare scenarios, malware detection misses can happen while processing SMTP traffic. 963593 In rare scenarios, when malware policy is applied on the Sensor, the Sensor can suddenly reboot due to low memory resources. 961617 [Failover] In rare scenarios, the Sensor reboots during trace upload. 961429 In a rare scenario, the Sensor reboots with exception when snort signatures are present. 957346 Customizing the Flow Packet logging on the Manager causes excessive packet logging from the Sensor to the Manager. This leads to database tuning failure, alert archival failure etc. 957173 The Sensor causes RST packets to be sent out of order. 945675 In extremely rare scenario, the traffic is not forwarded because of internal switch buffer exhaustion. 943598 In rare scenario with SSL and malware functionality enabled, the SSL attacks are not detected. 941194 During signature set update, the HTTP: Attempt to read password file attack may go undetected for a very short time. 923295 The Sensor incorrectly raises the "HTTP: Web Application Server Attack Detected" alert occasionally, when a user edits or submits information in the internal web application. 5
ID # Issue Description 908386 On rare occasions, the Application Visualization feature can cause database connectivity fault with the "sumbandwidth" error. 907976 In a failover pair after upgrade, the Active Fail-Open kit status switches between "Inline" and "Bypass".
