Itanium 64 Linux suffers security problems
RED HAT has updated the kernel for its Workstation 2.1 and Server 2.1 versions for Intel's Itanium after receiving notice of a "moderately critical" security flaw.
The flaw could cause a malicious remote user to interfere with computers running the operating systems.
According to Secunia.com, the updated package is available from the Red Hat Network, which you can find here.
