It's the end of the world. Again. According to some Linux developers and security researchers, a bug in the Linux kernel has just been uncovered that makes just about every distribution utilizing kernel 2.4 and 2.6 on just about all architectures since May of 2001 vulnerable to a certain kind of attack.

More recent kernels have a protection against this exploit, if they contain the mmap_min_addr feature is set correctly.
You can check your kernel via this:
# cat /proc/sys/vm mmap_min_addr
65536
While we have not gotten any official word from Redhat, I did some spot checking and it looks like RHEL 4.8, RHEL 5.2, and RHEL 5.3 have this parameter set correctly.
But, beware, any use of SELinux will bypass the protections given by this kernel feature.
