Resolution

New features/Enhancements New fixes
2.3.10
  • This release contains no new features or enhancements.
  • Issue:  Components of LiveUpdate Administrator contain log4j versions that are known to be an exposed vulnerability and may be impacted. Fix:  Install LiveUpdate Administrator 2.3.10 to upgrade log4j to version 2.16, which addresses the log4j vulnerability.   For more information, see:  Log4j2 vulnerability (CVE-2021-44228, CVE-2021-45046 and CVE-2021-45105) information and mitigation steps for on-premises manager and LiveUpdate Administrator
  • Issue: LiveUpdate Administrator reports a failure deleting files that were actually deleted.  Fix:  Changed the event logging code to not include the file names, which did not exist at the time of delete operation.
  • Issue:  LiveUpdate Administrator download task started to fail due to "Unknown exception while commit index info" exception.  Fix:  Increased the size of the concerned column of the table precondition to accommodate bigger precondition values. Updated the Postgres binaries to the latest from pgsql 10 series.
2.3.9
  • Create a customizable warning banner to appear on the login screen to deter unauthorized access.  The warning banner text is updated in the properties file.
  • You can now reach the LiveUpdate servers if you use an HTTPS proxy to handle traffic.
  • This release of LiveUpdate Administrator contains changes in the way the product uses the proxy host and port to make connections. LiveUpdate Administrator no longer uses the properties that have a JVM-wide impact.  Instead, LiveUpdate Administrator uses the local objects to create these connections, which stops LiveUpdate Administrator from inadvertently using proxies.  This new feature resolves the issue in which a few system properties were supposed to be applied only to one connection, but were unintentionally propagated to all connection objects.
2.3.8
  • You can upgrade from 2.3.1 and later to 2.3.8 on supported operating systems.  
  • LiveUpdate Administrator is packaged with the following updated third-party components (64-bit):

    • PostgreSQL 10.4
  • Fix ID 4134405: You upgrade Symantec Endpoint Protection to 14.0.1 and add its content to
    LiveUpdate Administrator’s Download Schedules. However, this action causes LiveUpdate
    Administrator to stop downloading content. Solution: Updated the processes by which content
    downloads to LiveUpdate Administrator.
  • Fix ID 4129120: The number of purged distribution center files reported in the LiveUpdate Administrator
    event log differs from the actual number of purged distribution center files. Solution: Refined the
    process by which files are tabulated as successfully deleted.

  • On the Home page, you can see the top 10 distribution centers that do not have the latest
    content revisions.
  • In previous releases, the contents in the distribution centers occasionally become corrupted
    and you have had to delete the contents manually. You can now delete the contents from a
    distribution center by clicking Configure > Distribution Centers > Edit > Select Desired location
    to clear > Wipe.
  • You can change the SMTP server port number on the Configure > Preferences page.

  • During the installation of LiveUpdate Administrator, the installation folder, temporary folder,
    and download folder cannot be empty. Also, the root drive (such as C:\ or D:\) must use a
    subfolder that does not contain other files. The subfolder should use a local path, as file share
    is not allowed. The similar validations are applicable on Preference page while changing
    Download and Temporary directory.
  • Removes non-supported products from Symantec Product Catalog.
  • To increase security, all administrator passwords to log on to LiveUpdate Administrator must
    be a minimum of 8 characters, be alphanumeric, and include one special character. For users
    using plain passwords without above recommendation, would still be able to log in into
    application with same password after upgrade to LUA 2.3.3.
  • The default protocol for Distribution Centers is HTTP. You can now configure the default
    Distribution Center to support either HTTP (7070) or HTTPS (7073), or the port that you
    configured when you installed LiveUpdate Administrator. The LiveUpdate Administrator URL’s
    now use the HTTPS protocol instead of the HTTP protocol.
  • The Export / Import workflow changes for LUA 2.3.0, LUA 2.3.1 and LUA 2.3.2. Please refer
    to the Procedure to import configuration section for more details.

2.3.2
  • Packaged with Apache Tomcat version 7.0.26 and PostgreSQL version 9.1.3. defects
  • Packaged with JRE 1.7 (private JRE, automatically bundled, installed, and configured by the
    LUA installer).
  • Enhanced security with advanced features to protect the user interface from certain attacks.
  • Added the ability to modify the LUA download directory path at any time (not just during installation).
  • Product Catalog now automatically updates to ensure catalog changes become available
    without any user initiated action being required.
  • Daylight savings time changes are now correctly handled for scheduled tasks.
  • Email notifications can be sent whenever a new LUA version is available, relevant catalog
    changes occur and as an early warning in advance of large monthly content downloads.
  • Enhanced content purging to ensure it works reliably, even if an external 3rd party source
    (e.g. Robocopy) is also accessing the content.
2.3.1
  • The LUA web server service now automatically restarts if it crashes or terminates
    unexpectedly.
  • LUA now automatically installs and uses an optimized private Java Runtime Environment
    (version 1.6 update 27). This also means it is no longer necessary to separately install a
    public JRE for use by LUA.
  • It is now possible for LUA to automatically run multiple specified distribution tasks after a
    download task completes.
  • New quick link added to the user interface which allows customers to quickly and easily
    capture all LUA-related troubleshooting information that Symantec Technical Support may
    require if answering a query or investigating a reported issue.
  • Other new quick links added to the user interface:
    • How to configure a Remote Distribution Center (Article and Video)
    • Product Selection Guide: Which sub-components to select (Article)
  • Added ability for LUA to automatically send email notification on successful completion of a
    task (as well as failure of a task).
  • LUA now automatically sends an email notification when disk space is running low on the
    drive to which LUA is installed (the LUA database is at risk of becoming corrupted if disk
    space runs low).
  • Email notification appearance has been enhanced (now HTML based).
  • Security within the user interface has been enhanced to ensure protection from specific
    potential attack scenarios.
  • LUA now periodically sends anonymous product information to Symantec
    (can be disabled if required).
  • LUA now installs and uses the latest available versions of Apache Tomcat (7.0.21) and
    PostgreSQL (9.0.4).
  • 25 other third-party components upgraded.

Note: Versions of LUA 2.3.0 and earlier use versions of PostgreSQL that have reached end of life. If you are using this earlier version, you should migrate to the latest version as soon as possible.

2.3.0
  • Rapid configuration export and restore.
  • LUA download tasks can now automatically resume and retry file downloads.
  • Event-driven email notification (with SMTP authentication support) to notify user(s) in case of
    download/distribution failures.
  • Ability to auto-start a distribution task after a specified download task.
  • Automatic LUA database maintenance, to ensure reliable and responsive operations.
  • Partially completed download and distribution tasks now show an accurate percentage of
    completion by the activity monitor.
  • Fast access to Symantec’s LUA best practice recommendations provided by the installation
    wizard and program menu.
  • Optimized load times for the LUA console home page and event log.

Resolved defects

  • Fix ID 2014599: Intermittent "Package is not trusted" errors for various product update files during LUA
    downloads (TECH141217)
  • Fix ID 2174087: Error: "value too long for type character varying(100) when processing
    1224848344jtun_enmssql-wxp-ix86.zip"
  • SYM11-005: LUA Cross-Site Request Forgery vulnerability (CVE-2011-0545,
    Security Response writeup)

Known issues

  • Usage of JRE version 6 update 24 or higher is strongly recommended, to ensure maximum application
    stability and security. Usage of previous versions, in certain situations, may lead to system instability
    and insecurity.
  • If hard disk space is extremely low on an LUA computer, it can cause tasks to fail and in turn, cause
    LUA to not clean up task related temp content files.
  • “Null%” can intermittently appear in relation to the completion percentage in the email notifications for
    failed distribution tasks.
  • If two download tasks attempt to access LUA’s temp directory at the same time, it can cause the
    following error to occur: “Failed to obtain write lock on content repository while committing download
    request id X”
  • Sometimes, the Tomcat service "LUA Apache Tomcat" stops after doing random and multiple
    navigations in the application. This issue can be solved by using the latest available server JVM (JDK)
    instead of a client JVM (JRE). Please use the following instructions:
    • Install the latest JDK 1.6 (note, it is JDK and not JRE)
    • Set your Path variable and JAVA_HOME to point to this JDK. To check if you are using the right
      Java in the path, open a command prompt and type java-version. It should show the version you
      had just downloaded and installed.
    • Server JVM is used. These steps are documented in TECH96391, in the Tomcat configuration section.
    • Restart the LUA Tomcat service from the Services control panel.
  • For proxy connection configurations for source, failover servers, and distribution locations, if FTP
    protocol is selected, application uses SOCKS to connect to a proxy server.
  • For browsing between pages, please use the toolbar and bread crumbs provided. Do not use the
    browser's Back button. Its usage can result in unexpected behavior.
  • Users are forced to save twice to add a Failover Server to a Source Server. When adding a failover
    server to a Source Server, you must first add and save the failover server details, and then save the
    Source Server record to fully commit the failover server addition. If not, the failover server is not added.
    The same is true for the Central LiveUpdate Server (CLU).
  • In Source Server and Distribution center configurations, application is supporting proxies with Basic
    and NTLM authentication. For configuring NTLM proxies in LiveUpdate Administrator, the user needs
    to specify Domain to which proxy is connected. There is no separate input field for entering domain
    name. User should enter proxy user name as "domain_name\user_name", which is domain_name
    followed by "\" and then user_name.
  • When a manual distribution is initiated by user, sometimes it takes more time to display activity
    monitor page when moving from page 2 of 2 of distribution wizard.
