Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2009:0459-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0459.html
Issue date: 2009-04-30
CVE Names: CVE-2008-4307 CVE-2009-0028 CVE-2009-0676
CVE-2009-0834
=====================================================================

1. Summary:

Updated kernel packages that fix several security issues and various bugs
are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, noarch, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, noarch, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, noarch, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, noarch, x86_64

3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security fixes:

* a logic error was found in the do_setlk() function of the Linux kernel
Network File System (NFS) implementation. If a signal interrupted a lock
request, the local POSIX lock was incorrectly created. This could cause a
denial of service on the NFS server if a file descriptor was closed before
its corresponding lock request returned. (CVE-2008-4307, Important)

* a deficiency was found in the Linux kernel system call auditing
implementation on 64-bit systems. This could allow a local, unprivileged
user to circumvent a system call audit configuration, if that configuration
filtered based on the "syscall" number or arguments.
(CVE-2009-0834, Important)

* Chris Evans reported a deficiency in the Linux kernel signals
implementation. The clone() system call permits the caller to indicate the
signal it wants to receive when its child exits. When clone() is called
with the CLONE_PARENT flag, it permits the caller to clone a new child that
shares the same parent as itself, enabling the indicated signal to be sent
to the caller's parent (instead of the caller), even if the caller's parent
has different real and effective user IDs. This could lead to a denial of
service of the parent. (CVE-2009-0028, Moderate)

* the sock_getsockopt() function in the Linux kernel did not properly
initialize a data structure that can be directly returned to user-space
when the getsockopt() function is called with SO_BSDCOMPAT optname set.
This flaw could possibly lead to memory disclosure.
(CVE-2009-0676, Moderate)

Bug fixes:

* a kernel crash may have occurred for Red Hat Enterprise Linux 4.7 guests
if their guest configuration file specified "vif = [ "type=ioemu" ]". This
crash only occurred when starting guests via the "xm create" command.
(BZ#477146)

* a bug in IO-APIC NMI watchdog may have prevented Red Hat Enterprise Linux
4.7 from being installed on HP ProLiant DL580 G5 systems. Hangs during
installation and "NMI received for unknown reason [xx]" errors may have
occurred. (BZ#479184)

* a kernel deadlock on some systems when using netdump through a network
interface that uses the igb driver. (BZ#480579)

* a possible kernel hang in sys_ptrace() on the Itanium® architecture,
possibly triggered by tracing a threaded process with strace. (BZ#484904)

* the RHSA-2008:0665 errata only fixed the known problem with the LSI Logic
LSI53C1030 Ultra320 SCSI controller, for tape devices. Read commands sent
to tape devices may have received incorrect data. This issue may have led
to data corruption. This update includes a fix for all types of devices.
(BZ#487399)

* a missing memory barrier caused a race condition in the AIO subsystem
between the read_events() and aio_complete() functions. This may have
caused a thread in read_events() to sleep indefinitely, possibly causing an
application hang. (BZ#489935)

* due to a lack of synchronization in the NFS client code, modifications
to some pages (for files on an NFS mounted file system) made through a
region of memory mapped by mmap() may be lost if the NFS client invalidates
its page cache for particular files. (BZ#490119)

* a NULL pointer dereference in the megaraid_mbox driver caused a system
crash on some systems. (BZ#493420)

* the ext3_symlink() function in the ext3 file system code used an
illegal __GFP_FS allocation inside some transactions. This may have
resulted in a kernel panic and "Assertion failure" errors. (BZ#493422)

* do_machine_check() cleared all Machine Check Exception (MCE) status
registers, preventing the BIOS from using them to determine the cause of
certain panics and errors. (BZ#494915)

* a bug prevented NMI watchdog from initializing on HP ProLiant DL580 G5
systems. (BZ#497330)

This update contains backported patches to fix these issues. The system
must be rebooted for this update to take effect.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
