    SubjectRe: [Cent OS 4.3] Bug in do_execve().
    From
    Hi,

    The current do_execve() doesn't have the bug.
    You should let CentOS team know the bug instead.

    > Kernel 2.6.9 has a bug that forgets to undo open_exec() in do_execve().
    > This bug was fixed in 2.6.10.

    > I noticed this bug remains in kernel-2.6.9-34.EL.src.rpm for Cent OS.
    > Distributors who use 2.6.9-based kernels, please check this.
