kernel Security update for Linux kernel (i386) Security update for Linux kernel (i386) This kernel update fixes the following security problems: - CVE-2006-3745: A double userspace copy in a SCTP ioctl allows local attackers to overflow a buffer in the kernel, potentially allowing code execution and privilege escalation. [#199441] - CVE-2006-4093: Local attackers were able to crash PowerPC systems with PPC970 processor using a not correctly disabled privileged instruction ("attn"). [#197810] - CVE-2006-3468: Remote attackers able to access an NFS of a ext2 or ext3 filesystem can cause a denial of service (file system panic) via a crafted UDP packet with a V2 lookup procedure that specifies a bad file handle (inode number), which triggers an error and causes an exported directory to be remounted read-only. [#192988] and the following non security bugs: - XEN patches/fixes: + kunmap_atomic() must zap the PTE to avoid dangling references. - Fix oops on io scheduler unload on a process without ioc (backport) - OCFS2 updated to to version 1.2.3. - update patches.arch/ppc-update_gtod-race.patch: restrict to 64bit only because it leads to deadlocks on ppc32 [#202146] - Fix MCA recovery in context switch path [#199472] - fix gettimeofday vs. update_gtod race [#197699] - LKCD: dump all slab pages.

This is now switched off. (see cat /proc/sys/kernel/hz_timer on the system) security This update can be used to install a new kernel. If you decide to use the kernel update, we recommend that you reboot your system upon completion of the YaST Online Update, as additional kernel modules may be needed which can only be loaded after the system is rebooted. If you are in the course of performing a new installation, you should deselect this kernel update in order to avoid problems with the hardware detection during the installation. kernel-bigsmp i586 f3136ea46bf61ff68b06e692c145ba8c73c48adf kernel-default i586 8ac3ad89d3d48fde7da1252824a41e2a571fb7ac kernel-smp i586 089338afaddaf6015b118001995a0d2eb551958a kernel-source i586 3537ff53e718dbd1bd059abe4d198a4b8365ca1f kernel-syms i586 46837ec111e8563073978c845f4ff90e77f3a48b
