OVERVIEW - -------- This kernel update fixes several bugs and vulnerabilities. A summary of the changes from the last kernel update are below. * Systems with more then one swap partition defined could OOPS when "swapoff -a" was run. * This update improves the kernel module loader vulnerability fix (CAN-2003-0127) initially fixed in ESA-20030318-009. * Using specially selected forged source addresses, a remote attacker can cause a very large number of collisions in the kernel's networking hash tables, resulting in a denial of service attack. The Common Vulnerabilities and Exposures project ( has assigned the name CAN-2003-0244 to this issue. * The "ioperm" system call does not properly restrict privileges, potentially allowing an unprivileged local user access to the I/O ports on the system.
