Red Hat Security Advisory RHSA-2001:013-05 - 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. Fixed in kernel 2.2.18-pre9.
