- Fixed / Added ELF loader error handling where it was missing, which could lead to a local privilege escalation. This was found by Paul Starzetz of isec.pl.
- Fixed several smbfs boundary checking problems which could lead to buffer overflows. This issue was found by Stefan Essern and was assigned the CVE ID CAN-2004-0883.
- Fixed a possible userspace corruptions / data disclosure problem on SMP machines with more than 4 GB of RAM.
- Fixed a denial of service condition in a.out support.
First, find out which kernel package to use, for example with
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with either:
- rpm -Fvh k_deflt-2.4.*.i586.rpm for the default kernel image, or
- rpm -Fhv k_athlon-2.4.*.i586.rpm for the AMD Athlon optimized kernel image, or
- rpm -Fhv k_smp-2.4.*.i586.rpm for the SMP kernel image, or
- rpm -Fhv k_psmp-2.4.*.i586.rpm for the PSMP kernel image
In case you are using LILO as bootmanager, please make sure that you also execute the command
after installing the update for the system to remain bootable.
Finally, reboot the system with
shutdown -r now
to load the new kernel (replace "now" with the appropriate amount of time to allow local users to cleanly log out, for example "+5" for five minutes.)
