Product(s): SUSE CORE 9 for AMD64 and Intel EM64T
- 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 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*.rpm for the default kernel image, or
- rpm -Fvh kernel-syms*.rpm kernel-smp*.rpm for the SMP kernel 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.)
