Linux developer warns of vulnerability allowing root access

One of the developers of the original Linux core has posted a vulnerability notice with details of a flaw that could allow a local user to assume control of a Linux computer.

Alan Cox, who worked with Linus Torvalds on the software that spawned the Linux operating system, sent an e-mail message to a mailing list for Linux kernel developers detailing a flaw in a debugging component known as ptrace.

Cox's employer, Red Hat, also posted a patch for Red Hat 7.1, 7.2, 7.3, and 8.0 at
