Product(s): Novell Linux Desktop 9 for x86_64
- CVE-2006-2936: The ftdi_sio driver allowed local users to cause a denial of service (memory consumption) by writing more data to the serial port than the hardware can handle, which causes the data to be queued. This requires this driver to be loaded, which only happens if such a device is plugged in.
- CVE-2006-5871: smbfs when UNIX extensions are enabled, ignores certain mount options, which could cause clients to use server-specified uid, gid and mode settings.
- CVE-2006-6106: Multiple buffer overflows in the cmtp_recv_interopmsg function in the Bluetooth driver (net/bluetooth/cmtp/capi.c) in the Linux kernel allowed remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via CAPI messages with a large value for the length of the (1) manu (manufacturer) or (2) serial (serial number) field.
- CVE-2006-6535: The dev_queue_xmit function in Linux kernel 2.6 can fail before calling the local_bh_disable function, which could lead to data corruption and "node lockups". This issue might not be exploitable at all for an attacker.
- CVE-2006-5749: The isdn_ppp_ccp_reset_alloc_state function in drivers/isdn/isdn_ppp.c in the Linux kernel does not call the init_timer function for the ISDN PPP CCP reset state timer, which has unknown attack vectors and results in a system crash.
- CVE-2006-5753: Unspecified vulnerability in the listxattr system call in Linux kernel, when a "bad inode" is present, allows local users to cause a denial of service (data corruption) and possibly gain privileges.
- CVE-2006-5754: The aio_setup_ring function in Linux kernel does not properly initialize a variable, which allows local users to cause a denial of service (crash).
- CVE-2007-1357: A denial of service problem against the AppleTalk protocol was fixed. A remote attacker in the same AppletTalk network segment could cause the machine to crash if it has AppleTalk protocol loaded.
- CVE-2007-1592: A local user could affect a double-free of a ipv6 structure potentially causing a local denial of service attack.
- A local denial of service was fixed in the USB visor driver, where local attackers could cause a huge amount of kernel memory to be allocated and so run the machine out of memory.
- CVE-2007-1353: The setsockopt function in the L2CAP and HCI Bluetooth support in the Linux kernel allows context-dependent attackers to read kernel memory and obtain sensitive information via unspecified vectors involving the copy_from_user function acces sing an uninitialized stack buffer.
- CVE-2006-7203: The compat_sys_mount function in fs/compat.c allows local users to cause a denial of service (NULL pointer dereference and oops) by mounting a smbfs file system in compatibility mode ("mount -t smbfs").

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
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.)
