Red Hat issued a security advisory Friday notifying customers that some of its servers were compromised last week due to a network attack. The company called the advisory critical and said it sent out the alert primarily for those who may obtain Red Hat binary packages via channels other than those of official Red Hat subscribers. The servers — for both the company’s commercial products and free versions of Linux — were breached; however, immediate action on the part of Red Hat prevented the attacker from gaining access to Red Hat Network, according to the company.
