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

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

This update addresses the following security issues :

- a memory leak in keyctl handling. A local user could use
this flaw to deplete kernel memory, eventually leading
to a denial of service. (CVE-2009-0031, Important)

- a buffer overflow in the Linux kernel Partial Reliable
Stream Control Transmission Protocol (PR-SCTP)
implementation. This could, potentially, lead to a
denial of service if a Forward-TSN chunk is received
with a large stream ID. (CVE-2009-0065, Important)

- a flaw when handling heavy network traffic on an SMP
system with many cores. An attacker who could send a
large amount of network traffic could create a denial of
service. (CVE-2008-5713, Important)

- the code for the HFS and HFS Plus (HFS+) file systems
failed to properly handle corrupted data structures.
This could, potentially, lead to a local denial of
service. (CVE-2008-4933, CVE-2008-5025, Low)

- a flaw was found in the HFS Plus (HFS+) file system
implementation. This could, potentially, lead to a local
denial of service when write operations are performed.
(CVE-2008-4934, Low)

- when fput() was called to close a socket, the
__scm_destroy() function in the Linux kernel could make
indirect recursive calls to itself. This could,
potentially, lead to a denial of service issue.
(CVE-2008-5029, Important)

- a flaw was found in the Asynchronous Transfer Mode (ATM)
subsystem. A local, unprivileged user could use the flaw
to listen on the same socket more than once, possibly
causing a denial of service. (CVE-2008-5079, Important)

- a race condition was found in the Linux kernel 'inotify'
watch removal and umount implementation. This could
allow a local, unprivileged user to cause a privilege
escalation or a denial of service. (CVE-2008-5182,

** Bug fixes and enhancements are provided for :

following manufacturers: Broadcom Chelsio Cisco Intel
Marvell NetXen Realtek Sun

- Fiber Channel support, including support for Qlogic
qla2xxx, qla4xxx, and qla84xx HBAs and the FCoE, FCP,
and zFCP protocols.

- support for various CPUs, including: AMD Opteron
processors with 45 nm SOI ('Shanghai') AMD Turion Ultra
processors Cell processors Intel Core i7 processors

- Xen support, including issues specific to the IA64
platform, systems using AMD processors, and Dell
Optiplex GX280 systems

- ext3, ext4, GFS2, NFS, and SPUFS

- Infiniband (including eHCA, eHEA, and IPoIB) support

- common I/O (CIO), direct I/O (DIO), and queued direct
I/O (qdio) support

- the kernel distributed lock manager (DLM)

- hardware issues with: SCSI, IEEE 1394 (FireWire), RAID
(including issues specific to Adaptec controllers), SATA
(including NCQ), PCI, audio, serial connections,
tape-drives, and USB

- ACPI, some of a general nature and some related to
specific hardware including: certain Lenovo Thinkpad
notebooks, HP DC7700 systems, and certain machines based
on Intel Centrino processor technology.

- CIFS, including Kerberos support and a tech-preview of
DFS support

- networking support, including IPv6, PPPoE, and IPSec

- support for Intel chipsets, including: Intel Cantiga
chipsets Intel Eagle Lake chipsets Intel i915 chipsets
Intel i965 chipsets Intel Ibex Peak chipsets Intel
chipsets offering QuickPath Interconnects (QPI)

- device mapping issues, including some in device mapper

- various issues specific to IA64 and PPC

- CCISS, including support for Compaq SMART Array
controllers P711m and P712m and other new hardware

- various issues affecting specific HP systems, including:
DL785G5 XW4800 XW8600 XW8600 XW9400

- IOMMU support, including specific issues with AMD and
IBM Calgary hardware

- the audit subsystem

- DASD support

- iSCSI support, including issues specific to Chelsio T3

- LVM issues

- SCTP management information base (MIB) support

- issues with: autofs, kdump, kobject_add, libata, lpar,
ptrace, and utrace

- platforms using Intel Enhanced Error Handling (EEH)

- EDAC issues for AMD K8 and Intel i5000

- ALSA, including support for new hardware

- futex support

- hugepage support

- Intelligent Platform Management Interface (IPMI) support

- issues affecting NEC/Stratus servers

- OFED support

- SELinux

- various Virtio issues

- when using the nfsd daemon in a clustered setup, kernel
panics appeared seemingly at random. These panics were
caused by a race condition in the device-mapper mirror

- the clock_gettime(CLOCK_THREAD_CPUTIME_ID, ) syscall
returned a smaller timespec value than the result of
previous clock_gettime() function execution, which
resulted in a negative, and nonsensical, elapsed time

- nfs_create_rpc_client was called with a 'flavor'
parameter which was usually ignored and ended up
unconditionally creating the RPC client with an
AUTH_UNIX flavor. This caused problems on AUTH_GSS
mounts when the credentials needed to be refreshed. The
credops did not match the authorization type, which
resulted in the credops dereferencing an incorrect part
of the AUTH_UNIX rpc_auth struct.

- when copy_user_c terminated prematurely due to reading
beyond the end of the user buffer and the kernel jumped
to the exception table entry, the rsi register was not
cleared. This resulted in exiting back to user code with
garbage in the rsi register.

- the hexdump data in s390dbf traces was incomplete. The
length of the data traced was incorrect and the SAN
payload was read from a different place then it was
written to.

- when using connected mode (CM) in IPoIB on ehca2
hardware, it was not possible to transmit any data.

- when an application called fork() and pthread_create()
many times and, at some point, a thread forked a child
and then attempted to call the setpgid() function, then
this function failed and returned and ESRCH error value.
