Red Hat Protects Supposedly Invincible Code against Malware

Red Hat Protects Supposedly Invincible Code against Malware

Linux, which according to modern myth is supposed to be virus-proof, is on its way to supporting the NX (No Execute) security widgetry that the x86 chipmakers are building into their processors.

As its name suggests, NX is meant to block worms and virus from executing their payloads and curtail the bevy of nasties that exploit vulnerable buffer overflows, a source of half the world's intrusion headaches these days.

To work, the widgetry needs operating system support. Microsoft's XP Service Pack 2 is supposed to support NX when it arrives later this year.

Based on initial code provided by Intel, Red Hat has thrown some prototype software into the collective Linux kernel pot and has put it into its Fedora Core 2 early developer code. It intends to put it in the Red Hat Enterprise 3 update later this year and the Enterprise 4 release next year.

The patch may inhibit some legacy software from working.
