KB5025272 is the security-only update for Windows Server 2012. It was released under April month’s ‘Patch Tuesday’ program of Microsoft. We look at the significant points of the KB5025272 security update below.

Key points about the KB5025272 for Windows Server 2012

  • KB5025272 is a standalone security update. Standalone security updates work as independent updates. This update will have no correlation with any previous security update.
  • March month’s security update can be found on the KB5023752 page.
  • For adequate security coverage, all the security updates need to be installed on Windows Server 2012.
  • Usually, it is a better idea to patch Windows Server 2012 with monthly rollup updates instead of security-only updates. This is because the monthly rollup updates are cumulative in nature. Also, installing security-only updates has additional overheads.
  • KB5025272 contains only security changes for Windows Server 2012.
  • KB5023791 is the Servicing Stack Update that needs to be deployed on Windows Server 2012 prior to installing KB5025272.
  • KB5022835 is the cumulative update for Internet Explorer. This update needs to be installed alongside the security update KB5025272 for full protection on the server. KB5022835 was released in February 2023. If you have deployed February or March months’ security update, then KB5022835 should have already been deployed on the server.
  • 62 security vulnerabilities affect Windows Server 2012 as per April month’s security bulletin for Windows Server 2012. Out of these, 6 vulnerabilities have a ‘CRITICAL’ impact on the server. Details of these CRITICAL vulnerabilities are shared in the vulnerability section.

As you would have seen, April month’s security coverage for Windows Server 2012 will involve installing KB5023791, KB5022835, and KB5025272 in the proper sequence.
