solutions Security update for Linux kernel SuSE Linux Maintenance Web (61e58cdb1f1faaad69c14fac628319c3)
Product(s): SuSE Linux Desktop 1.0
- 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.
- On the i386 platform, the LDT was not always cleared in the correct context.
- A local denial of service against the auditing system was fixed.
- IRQ safety issues in the gendisk layer were fixed.
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.)
