  • This release includes the following LEM Manager and LEM Agent updates:
    • LEM Manager Hotfix 6
    • LEM Agent Hotfix 5
  • If you applied LEM Agent Hotfix 5 last release, you only need to install LEM Manager Hotfix 6. If you did not apply LEM Agent Hotfix 5 last release, apply LEM Agent Hotfix 5 and LEM Manager Hotfix 6 at the same time.

Fixed Issues

Hotfix 6 includes three updates.

Functional Issues Fixed in Hotfix 6

LEM Manager updates in this release:

  • Fixed an expired certificate for connector updates.

  • Updated the partition delete process to prevent it from running before the LEM Manager starts up.

  • Fixed a NullPointerException error caused by the partition delete process.  

LEM Agent updates in this release:

  • No new LEM Agent updates.

Issues Fixed in Previous Hotfixes

The following fixes from Hotfix 1, Hotfix 2, Hotfix 3, Hotfix 4, and Hotfix 5 are also included in this hotfix:

  • Added several updates to improve logging and enhance supportability.

  • Upgraded Tomcat to version 8.0.44.

  • Fixed an issue with free disk calculations.

  • Upgraded the SSH library to support AES encryption by default.

  • Windows Server 2016 nodes are now labeled properly in the LEM console. Previously, the LEM console listed computers running Windows Server 2016 as Windows NT (unknown).

  • Fixed a hard-coded credential vulnerability (CWE Classification 798). 

  • Addressed several security issues.
  • Made multiple updates that improve communication with the LEM Agent.
  • Fixed an issue related to free disk space management. Previously, LEM might under-report the amount of disk space remaining if raw logging was enabled.
  • Added updates that improve the performance of some connectors. In addition, fixed a bug that caused a connector to not function properly.
  • Fixed a CMC command vulnerability.
  • Scheduled nDepth search: results limited to 50,000.
  • Fixed an ImportCert error that occurred when importing certificate after a command failure.
  • Fixed an issue that displays the IP address instead of the FQDN/hostname on the "All Installed Agents" screen.
  • Fixed an issue that occurred when an L4 Database appliance started with only 128MB of memory.
  • Updated the Java platform to the latest version.
  • Fixed an out-of-memory issue that occurred when sending alerts to the console. The fix improves performance when a large number of events are sent to the console.
  • Fixed Agent–Manager communication issues: periodic disconnect and others.
  • Fixed an issue with nDepth log retention (logging missing date in raw records).
  • Fixed an issue that prevented logging in to LEM if using UserPrincipalName with a custom Alias, or SAMAccountName with NETBIOS.
  • Added the ability to use sub-alias LDAP environments.
  • Removed field limitations in the normalized alert database.
  • Fixed a log rotation issue that caused connectors to stop working if log lines were too long.
  • Fixed a single sign-on (SSO) issue that occurred if a Kerberos ticket was unusually long because a user belonged to many groups.
  • Added the ability to configure custom LDAP groups for authentication.
  • Set an Agent memory limit for Agents upgraded from older versions.
  • Fixed other Agent–Manager communication issues.
  • Added improvements to assist customer support, including improved logging, and added diagnostics.
  • LEM can again download threat-feeds IPs. This issue occurred when the threat-feeds server certificate changed.
  • Updated the Active Directory (LDAP) configuration. You can now have a domain name containing a dash.
  • You can now recover a password when HTTP is disabled.
  • Exceptions during a fast evaluation are now logged.
