Scientific Linux Security Update : kernel on SL5.x i386/x86_64

Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

These new kernel packages fix the following security issues :

A flaw was found in the virtual filesystem (VFS). An unprivileged
local user could truncate directories to which they had write
permission
this could render the contents of the directory
inaccessible. (CVE-2008-0001, Important)

A flaw was found in the Xen PAL emulation on Intel 64 platforms. A
guest Hardware-assisted virtual machine (HVM) could read the arbitrary
physical memory of the host system, which could make information
available to unauthorized users. (CVE-2007-6416, Important)

A flaw was found in the way core dump files were created. If a local
user can get a root-owned process to dump a core file into a
directory, which the user has write access to, they could gain read
access to that core file, potentially containing sensitive
information. (CVE-2007-6206, Moderate)

A buffer overflow flaw was found in the CIFS virtual file system. A
remote,authenticated user could issue a request that could lead to a
denial of service. (CVE-2007-5904, Moderate)

A flaw was found in the 'sysfs_readdir' function. A local user could
create a race condition which would cause a denial of service (kernel
oops). (CVE-2007-3104, Moderate)

As well, these updated packages fix the following bugs :

- running the 'strace -f' command caused strace to hang,
without displaying information about child processes.

- unmounting an unresponsive, interruptable NFS mount, for
example, one mounted with the 'intr' option, may have
caused a system crash.

- a bug in the s2io.ko driver prevented VLAN devices from
being added. Attempting to add a device to a VLAN, for
example, running the 'vconfig add [device-name]
[vlan-id]' command caused vconfig to fail.

- tux used an incorrect open flag bit. This caused
problems when building packages in a chroot environment,
such as mock, which is used by the koji build system.
