6. In which release will this issue be resolved?

Note: These hotfixes are no longer publicly available, as their fixes are included in the releases mentioned above. If this issue is experienced, the supported resolution is to upgrade to the latest version.

Deduplication Appliances: A fix for this vulnerability is targeted for inclusion in Deduplication Appliances 1.4.5.  A hotfix for 1.4.4 is attached to this document.  This hotfix includes a README containing installation instructions.

Note: This hotfix is no longer publicly available, as its fixes are included in the 1.4.5 release update. If this issue is experienced, the supported resolution is to upgrade to the latest version.

PLEASE NOTE!  After this hotfix has been installed on an Appliance, rollback is not supported.  In addition, if a 2.5.x hotfix is installed on an Appliance, a future upgrade to 2.5.4 will not be possible; only an upgrade to 2.6.0.x will be possible.  If there are plans to upgrade an affected Appliance to 2.5.4, the hotfix should not be applied until after the upgrade, when the 2.5.4 hotfix should be applied.

Once a 2.6.0.x hotfix has been applied, it does not need to be reapplied even if upgrading to another affected 2.6.0.x - for example, if the hotfix is applied to an Appliance at, and the Appliance is later upgraded to, the hotfix will still be installed on the Appliance and thus will not need to be reinstalled.

However, if a 2.5.x hotfix is applied and the Appliance is later upgraded to an affected 2.6.0.x version, the 2.6.0.x ( EEB must be applied after the upgrade - unless it is upgraded to or above.

If the Appliance is upgraded to or later, a hotfix will not be required as these versions will already contain an updated bash which is not affected by these vulnerabilities.

NetBackup Appliances is now available - download and README information can be found in the Related Article linked below.

As always, Veritas Corporation always recommends running NetBackup environments using the latest available version whenever possible.
