- when creating directories on ext2 filesystems the kernel did not zero initialize the memory allocated. Therefore potentially sensitive information could be exposed to users (CAN-2005-0400).
- local users can crash the kernel via a crafted ELF library or executable, which causes a free of an invalid pointer (CAN-2005-0749).
- local users could gain root access by causing a core dump of specially crafted ELF executables (CAN-2005-1263).
- fix files beeing truncated to four gigabytes on ext3
- fix entries in /proc that caused 'top' to crash
- fix kernel crash caused by busy inodes after umount
- fix data corruption issue in MD multipath when retrying failed IO
- enhanced locking in MD multipath and raid1
- fix endless loop in IPsec
- fix crash in XFS filesystem
- fix write performance problems on machines with more than 1GB memory
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.)
