Last month I blogged about a vulnerability found on OWC ActiveX components that affects ISA Server and how you can check if your system is vulnerable. On this month´s security bulletins Microsoft releases a security patch to solve this issue.
Altough ISA Server is not compromised, unless the firewall administrator uses ISA as a workstation (i.e. accessing internet web sites from the firewall). It is always good to keep the system up to date.
For more information about this month´s security updates, read August Security Bulletin Summary.
If you want to download the patch check MS09-043 bulletin.
