Scientific Linux Security Update : kernel on SL4.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

These updated kernel packages fix the following security issues :

A flaw was found in the virtual filesystem (VFS). A local unprivileged
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 implementation of ptrace. A local unprivileged
user could trigger this flaw and possibly cause a denial of service
(system hang). (CVE-2007-5500, Important)

A flaw was found in the way the Red Hat Enterprise Linux 4 kernel
handled page faults when a CPU used the NUMA method for accessing
memory on Itanium architectures. A local unprivileged user could
trigger this flaw and cause a denial of service (system panic).
(CVE-2007-4130, Important)

A possible NULL pointer dereference was found in the chrp_show_cpuinfo
function when using the PowerPC architecture. This may have allowed a
local unprivileged user to cause a denial of service (crash).
(CVE-2007-6694, Moderate)

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. This could potentially grant unauthorized
access to sensitive information. (CVE-2007-6206, Moderate)

Two buffer overflow flaws were found in the Linux kernel ISDN
subsystem. A local unprivileged user could use these flaws to cause a
denial of service. (CVE-2007-6063, CVE-2007-6151, Moderate)

As well, these updated packages fix the following bug :

- when moving volumes that contain multiple segments, and
a mirror segment is not the first in the mapping table,
running the 'pvmove /dev/[device] /dev/[device]' command
caused a kernel panic. A 'kernel: Unable to handle
kernel paging request at virtual address [address]'
error was logged by syslog.
