    Bug exposes eight years of Linux kernel

    Linux developers have issued a critical update for the open-source OS after researchers uncovered a vulnerability in its kernel that puts most versions built in the past eight years at risk of complete takeover.

    The bug involves the way kernel-level routines such as sock_sendpage react when they are left unimplemented. Instead of linking to a corresponding placeholder, (for example, sock_no_accept), the function pointer is left uninitialized. Sock_sendpage doesn't always validate the pointer before dereferencing it, leaving the OS open to local privilege escalation that can completely compromise the underlying machine.

    Full Story: here
    I'm sure theres a dig to be had here somewhere...

      With all the vociferousness about how secure Open-source is. As the popular saying goes, "Too many cooks spoil the broth". Actually, I don't seem surprised. :D
