solutions Security update for Linux kernel SuSE Linux Maintenance Web (b82467862cb95a39a359829959673c39)
Product(s): SUSE CORE 9 for Itanium Processor Family
- With the iptables firewall enabled in a certain configuration (as done by SuSEFirewall2) a handcrafted IP packet from a remote attacker could crash the machine.
- s390: The privileged "sacf" instruction was not correctly protected, so local users could gain root access.
- Some minor addition proc information leaks were fixed.
- 2 CD writing problems were fixed, one in BIO handling and one in highmem bounce buffer handling (machines with more than 1GB RAM).
- A problem with write barriers not being issued on IDE drives that default to write cache off was fixed.
- Make sure O_SYNC writes return -EIO for write errors.
- Some bio related fixes for the ASMlib kernel driver.
- Support for O_NOATIME in open(2) system call, fixing an LVM related problem.
- Do not clear/remove referenced pages in BLKFLSBUF ioctl.
- Fixed an iptables logging Oops caused by ifdown/ifup sequences.
- Do not propagate TCP errors to nfsd to avoid having nfsd dieing.
- Fixed some RAID 1 problems for read retry problems and device removal.
- Do not dirty inherited ACLs.
- Don't attach upper level SCSI drivers to raid control ports, such as the LSI/Engenio.
- Fixed a USB 2.0 EHCI problem with list scanning on SMP systems.
- Fixed a memory corruption in libata.
- ia64: Fixed a race in fsys_gettimeofday on IPF.
- ia64: Fixed crash in perfmonctl syscall.
First find out which kernel package to install by using the following command:
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with either:
rpm -Fvh kernel-syms*.rpm kernel-default*.rpmfor the default kernel image, or
rpm -Fvh kernel-syms*.rpm kernel-64k-pagesize*.rpmfor the 64k page size kernel image, or
rpm -Fhv kernel-syms*.rpm kernel-sn*.rpmfor the SGI SN2 (Altix) image
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.)
