Product(s): SUSE CORE 9 for Itanium Processor Family
- An unlocked VM operation could lead to a local user gaining root access using a handcrafted ELF binary and the uselib system call. This problem was found by Paul Starzetz and has been assigned the Mitre CVE ID CAN-2004-1235.
- A race condition in the SMP page fault handler could lead to a local attacker gaining root access on SMP machines. This problem was also found by Paul Starzetz and has been assigned the Mitre CVE ID CAN-2005-001.
- A problem in the earlier cmsg / sendmsg security fix was identified and fixed which could lead 32bit applications on a 64bit system (like i386 binaries on x86_64, or PowerPC binaries on a PowerPC64 system) to handle the sendmsg call incorrectly.
- An incomplete fix of the IGMP problem in the last update was replaced by the final approved fix.
- The smbfs fixes done 2 security updates ago were broken for writing files. This has been fixed.
- grsecurity reported a possible signedness problem in the generic scsi ioctl handler.
- Bad handling of oversized NFS Direct I/O request could lead to a local denial of service attack.
First, find out which kernel package to download and use, for example with
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.)
