Product(s): SUSE CORE 9 for Itanium Processor Family
- CAN-2005-0449: The netfilter/iptables module in Linux before 220.127.116.11 allows remote attackers to cause a denial of service (kernel crash) or bypass firewall rules via crafted packets, which are not properly handled by the skb_checksum_help function.
- CAN-2005-0209: When forwarding fragmented packets, we can only use hardware assisted checksum once.
- CAN-2005-0529: Linux kernels before 2.6.11 use different size types for offset arguments to the proc_file_read and locks_read_proc functions, which leads to a heap-based buffer overflow when a signed comparison causes negative integers to be used in a positive context.
- CAN-2005-0530: Signedness error in the copy_from_read_buf function in n_tty.c before Linux kernel 2.6.11 allows local users to read kernel memory via a negative argument.
- Missing checking in the epoll system calls allowed overwriting of a small range of kernel memory.
- A integer overflow was possible when writing to a sysfs file, allowing an attacker to overwrite kernel memory.
- CAN-2005-0136: Fixed a local denial of service problem on ia64 which was possible to trigger by using the ptrace system call.
- CAN-2005-0532: The reiserfs_copy_from_user_to_file_region function in reiserfs/file.c before Linux kernel 2.6.11, when running on 64-bit architectures, may allow local users to trigger a buffer overflow as a result of casting discrepancies between size_t and int data types.
- CAN-2005-0135: Fixed a local denial denial of service problem against unwind on the IA64 platform.
- CAN-2005-0384: Fixed a local denial of service attack in the kernel PPP code.
- CAN-2005-0210: A dst leak problem in the ip_conntrack module of the iptables firewall was fixed.
- CAN-2005-0504: Buffer overflow in the MoxaDriverIoctl function for the moxa serial driver (moxa.c) in Linux 2.2.x, 2.4.x, and 2.6.x allows local users to execute arbitrary code via a certain modified length value.
- Only root should be able to set the N_MOUSE line discipline, this is a partial fix for CAN-2004-0814.
- Due to an xattr sharing bug in the ext2 and ext3 filesystems, default ACLs could disappear.
- Superblock updates that experience write failures to a software raid component device, do not fail the device out of the software raid.
- Fixed the raw device ioctl to correctly use userspace pointers.
- Assigning a IPv6 address to a pppd device could crash the kernel.
- mdadm did not correctly activate multipath configurations.
- Fixed md multipath assembly and various md RAID races.
- Reading specific /proc files (like for instance the 'ps' command does) could crash the system under some circumstances.
- Fixed a problem in toss_page_cache_nodes introduced by SP1.
- amd64: CMP numa node detection for AMD dual core backport added.
- Fixed glibc "make check" problem by fixing bogus ECHILD return values from wait* function when the group leader already was a zombie process.
- Fix releasepage on delalloc buffers with small blocksizes on XFS filesystems.
- Prevent a race condition between skb_unlink and kfree_skb in ARP handling.
- Fix endless loop when syncing an array that doesn't need any resync.
- Fixed a slow memory leak on superblock updates.
- Various bugs in XFS / NFS filesystem interaction were fixed.
- Fixed a problem in the aio-stress testcase on XFS.
- Enabled the missing heap-stack-gap sysctl.
- Redundant Write-Back in Receive Descriptor Ring caused memory corruption in the ixgb gigabit ethernet card driver.
- Fixed a deadlock due to race between truncate and direct io write in the XFS filesystem.
- Fixed a performance problem in DMAPI by dropping the big kernel lock temporary.
- Fixed some XFS hash performance problems.
- Fix PDH console on HP rx1600.
- Allow allocating shared mem segments bigger than 2 GB.
- NSS: Several stability problems were fixed.
- antivir / dazuko.ko: The capability handling of this module was broken and was fixed by a version upgrade.
- drbd: A slow memory leak in drbd was fixed.
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.)
