VMware Carbon Black App Control 8.9.0 | 24 APR 2023 | Build 8.9.0.1454.624 Check for additions and updates to these release notes. |
Due to an issue discovered after the release of 8.9.0, we DO NOT recommend upgrading to or installing the Windows 8.9.0 agent on any file share or network share servers in your environment without first reviewing this UEX Knowledge Base article. Failure to properly configure your file or network share(s) may result in delays modifying files or otherwise leave your server unusable.
Starting with the 8.9.4 App Control server, valid signing certificates are required for all files contained in Windows App Control agent installation packages. In February 2023, the signing certificate used to validate SHA-1 MSI's in the 8.9.4 server expired, which prevents any future Windows App Control agent installation packages from being properly validated and installed with this server version.
We recommend both customers who do and do not use Windows XP/2003 on 8.9.4 server upgrade to 8.9.6 server to ensure there are no issues with future release installations. The 8.9.6 Server contains an updated SHA-1 signing signature required to validate future installation packages of the Windows App Control agent.
Customers who do not wish to upgrade to 8.9.6 server must manually apply the new SHA-1 signing certificate to prevent these issues from occuring. You can download this new signing certificate here.
