The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier,
does not properly clear the current->clear_child_tid pointer, which allows
local users to cause a denial of service (memory corruption) or possibly
gain privileges via a clone system call with CLONE_CHILD_SETTID or
CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread
creation and exit.
