Three security holes fixed in new kernel

Three security holes fixed in new kernel, and several other
updates and bug fixes have been applied as well.

Three security holes have been fixed in the kernel. One involves
ptrace, another involves sysctl, and the last is specific to some
Intel CPUs. All three security holes involve local access only
(they do not provide a hole to remote attackers without a local
account). The ptrace and sysctl bugs provide local users with the
potential to compromise the root account. Neither has an active
exploit available at the time of this writing. The last security
hole is a DOS (Denial Of Service) that does not provide access to
the root account but does allow any user with shell access the
ability to halt the CPU.

All users are strongly recommended to upgrade.

In addition to the security fixes, these kernels contain more
advanced support for the Intel Pentium 4 processors, as well as
a number of driver updates. These updates include e100, sis900,
cs46xx, qla1x160, qla2x00, ServeRAID, and ipvs.

In addition, a number of other bugs have been fixed. Most notably,
the RAW I/O facility could corrupt data under certain usage patterns.
