- 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
This kernel update also contains the IBM 2005-04-28 kernel 2.4.21 bug fix patch 25 which fixes the following issues:
- lcs: fix system hang when registering of multicast addresses fails.
- qeth: fix VLAN malformed unicast packets in layer 2 mode.
- qeth: do not allow layer 2 mode in case of Hipersocket devices.
- s390dbf: use more specific permissions for procfs files.
- scsi: fix LVM being unable to re-enable a path after a cable pull.
- z90crypt: fix kernel Oops while writing to
- zfcp: increase retrying of exchange config data requests up to 2 minutes.
rpm -Fvh k_deflt.rpm zipl
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.)
