McAfee update glitch kills email servers

A glitched update released last week caused McAfee security products to crash, affecting email systems. 

The affected update (DAT 66822) was pushed out to corporate customers and affected six McAfee poducts including email and web security, email gateway, and GroupShield. McAfee said users should not upgrade to the affected DAT file and instead apply the subsequent fixed update (DAT 66823).

Sydney IT administrator Jackie Chen said the error caused his large organisation’s Exchange server to crash. “The bloody McAfee [sic] caused another trouble yesterday by re-releasing the new DAT 6682,” he said. “The only thing you can do is to revert the DAT back to 6681 in both ePO master repository and the mail server.”
