Product(s): SUSE CORE 9 for x86
Novell Linux Desktop 9 for x86
- CAN-2004-1068: Missing serialization in unix_dgram_recvmsg() could lead to elevated privileges, making it possible for a local attacker to gain root access. Thanks to Paul Starzetz for pointing out this problem.
- CAN-2004-1016: Missing integer overflow checks in sendmsg / control message handling allows a local attacker to crash or halt the machine. This was independent found by Paul Starzetz and Georgi Guninski, and fixed by Herbert Xu.
- A memory leak in the IP option handling in the sendmsg() system call that was reported by Georgi Guninski.
- CAN-2004-1137: Some of the pointer handling in the Linux IGMP code was broken and could allow a local attacker to crash the machine. This was found by Paul Starzetz and fixed by Chris Wright.
- A memory leak in ip_conntrack_ftp connection handling was fixed.
- A local denial of service in aio_free_ring allows a local attacker to crash the machine.
- A problem in the memory management handling of ELF executables could lead to a local attacker crashing with a handcrafted ELF binary.
- CAN-2004-1151: A buffer overflow in the system call handling in the 32bit system call emulation on AMD64 / Intel EM64T systems could lead to a local privilege escalation or denial of service condition.
- Fixed a remote denial of service problem in the NFS kernel service, allowing a remote attacker with NFS access to a machine to remotely crash the kernel.
- A vfree() was called with interrupts disabled in the SCSI generic device handling, which could lead to a hanging machine.
- A race condition between a file unlink and umount could lead to a machine crash.
- Fixed a small memory leak in bio_copy_user().
- cdrecord -scanbus could crash the kernel when using the "gdth" SCSI driver.
- Allow reading from zeropage (/dev/zero) using O_DIRECT/rawio.
- Fixed some LSB issues in the fcntl compatibility handling.
- The st (SCSI tape) driver did not pass on generic SCSI ioctl commands to the SCSI midlayer.
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 the kernel symbols (kernel-syms*.rpm) and install it with either:
- rpm -Fvh kernel-syms*.rpm kernel-default*.rpm for the default kernel image, or
- rpm -Fhv kernel-syms*.rpm kernel-smp*.rpm for the SMP kernel image with support for up to 64 GB, or
- rpm -Fhv kernel-syms*.rpm kernel-bigsmp*.rpm for the SMP kernel image with support for up to 64 GB
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
