1 Manager-NS-series Release Notes McAfee Network Security Platform 9.1 Revision A Contents About this release New features Enhancements Resolved issues Installation instructions Known issues Product documentation About this release This document contains important information about the current release. We recommend that you read the whole document. Network Security Platform follows a release process that is based on customer requirements and best practices followed by other McAfee teams. For details, read KB This release of Network Security Platform is to provide new features and enhancements on the Manager and NS-series Sensor software. Release parameters Version Network Security Manager software version Signature Set NS-series Sensor software version 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 1.8.0_131, it is no longer possible to do so, and the Manager uses port 4166 as the UDP source port to bind for IPv6. 1

2 Manager 9.1 uses JRE version 1.8.0_131. 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. Manager software version 9.1 is not supported on McAfee-built Dell-based Manager Appliances. McAfee recommends that you use Intel-based Manager Appliances instead. Upgrade support McAfee regularly releases updated versions of the signature set. You can choose to automatically download and deploy the signature set in the Manager. Consider the following before upgrading to Network Security Manager version 9.1: If you are using the Manager version with McAfee Cloud Threat Detection (McAfee CTD) environment only, then you can upgrade to Manager version 9.1. This version supports integration with McAfee CTD. If you are on Manager version , note that the Manager version 9.1 does not support the KVM and NSX environments. In this case, McAfee recommends you to continue using the Manager version Manager version does not support NS-series Sensor version The following is the upgrade matrix supported for this release: Component Minimum Software Version Manager/Central Manager software 8.1: , : , (only for McAfee CTD), : NS-series Sensor software (NS3x00, NS5x00, NS7x00, NS9x00) NS9x00, NS7x00 8.1: , : , NS5x00, NS3x00 8.1: , : , Heterogeneous support This version of 9.1 Manager software can be used to configure and manage the following devices: Device NS-series Sensors (NS3100, NS3200, NS5100, NS5200, NS7100, NS7200, NS7300, NS9100, NS9200, NS9300) NS-series Sensors (NS7150, NS7250, NS7350) 9.1 Virtual IPS Sensors (IPS-VM100 and IPS-VM600) Network Security Manager version 9.1 does not support KVM environment.

Resolved Manager software issues This release does not contain any resolved issues for the Manager. 3

4 Resolved Sensor software issues The following table lists the high-severity Sensor software issues: ID # Issue Description [NS9300] Packets are dropped due to improper distribution of MPLS traffic. The following table lists the medium-severity Sensor software issues: ID # Issue Description The Sensor reads the incorrect input without proper validation and starts establishing trust using SHA2 based signature methods Log errors such as Port Speed Unknown are raised for 10G and 40G ports Alerts are generated even after layer 7 DDoS response status is disabled A Sensor reboot is required to reflect the speed change in the management port The Sensor logs have text error in the reboot message The Sensor does not switch to layer 2 mode when the link to an interconnect port fails Invalid < and > characters are sent as part of URL information to Advanced Threat Defense In the Sensor, the Ignore Rule does not work when same TCP/HTTP based protocol packet in the flow is resent After an upgrade, the Sensor experiences exception while processing signature set that causes it to go to bad health or experience auto recovery. This happens more often when there are Ignore Rule with Any Any or IPv6 Ignore Rule and IPv6 scanning is disabled The Sensor fails to decrypt SSL traffic due to which attacks are not detected Configuration update fails after a certain number of times when there are Ignore Rule with Any Any or IPv6 Ignore Rule and IPv6 scanning is disabled. Internal resources fail to free for such configurations Invalid characters are sent as URL information to Advanced Threat Defense Out-of-order TCP segments are queued for download which results in timeout or in exceptionally long delays Incorrect alert is generated for high layer 2 drop in the Manager The Sensor cannot extract the file name when SMTP traffic has multiple attachments After Sensor upgrade, FTP traffic does not flow through the Sensor For XFF traffic, the Sensor does not send true client's IP address to syslog server [NS9300] For a failover pair, when the Sensor switches from layer 2, the packets loop Syslog alerts sent from the Sensor displays the timestamp incorrectly with a 12-hour difference Filename and domain in URL path contains duplicate domain name information when submitted to Advanced Threat Defense Whitelisted entries with more than two labels does not generate an exact match Sensor reboots or auto recovers when entries to the IP Reputation caches are added even after reaching the maximum table size The Sensor fails to plot the interface throughput statistics In a rare condition, the malware processing engine experiences an exception while processing an SMTP attachment file having large encoded content Internal resource leak in the malware processing modules causes the Sensor to stop sending files to the Advanced Threat Defense appliance Port throughput utilization is miscalculated for ports with speed greater than 1G The output for resolve gti server CLI command displays incorrect destination. 4

5 ID # Issue Description In a rare condition, the Sensor crashes during initialization and triggers auto recovery [NS9300] DNS packets are duplicated multiple times when connected in a failover mode Layer 7 DDOS response action configuration does not work correctly / Sensor fails to trigger a match in a SNORT rule when the pattern is embedded in a HTTP response beyond 256 bytes [NS7x00, NS5x00, NS3x00] Links are flapping randomly because of incorrect internal ports timeout configuration The link on the interfaces of the Sensor suddenly switches on and off FTP file transfer cannot be blocked with advanced malware policy The Sensor fails to block retransmitted packets for malware attacks configured for blocking. 5
