Patch Tuesday: June, 2009: Patch Tuesday Analysis: Something for Everyone

If you administer workstations, servers, IIS servers or domain controllers pay attention to the patches this month.  Here's my thoughts by system category and then the chart follows.

All systems

For this new print spooler vulnerability, apply MS09-22 or disable the service.  Make sure you understand MS09-026 before deciding to forgo installation; in general we recommend installing after normal testing. 

Workstation/Terminal Services Patches

Install MS09-024 even if though your users don't use MS Works; the bad guys don't mind using Works to send malicious files.  Install MS09-019 as as possible after minimal testing since exploit details are public.  Install MS09-23, MS09-021 and MS09-027 after normal testing.  MS09-025 is only an issue for those of you with least privilege workstation environments. 

IIS Servers

Install MS09-020 after normal to minimum testing; exploit details are public.

Domain Controllers

Start testing MS09-018 right away and get it installed thereafter.  Exploit details are not public but domain controller vulnerabilities expose your entire forest to risk.
