                   Red Hat Security Advisory

Synopsis:          Important: kernel security, bug fix, and enhancement update
Advisory ID:       RHSA-2010:0394-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0394.html
Issue date:        2010-05-05
CVE Names:         CVE-2010-0729 CVE-2010-1083 CVE-2010-1085 
                   CVE-2010-1086 CVE-2010-1188 
=====================================================================

1. Summary:

Updated kernel packages that fix multiple security issues, several bugs,
and add three enhancements are now available for Red Hat Enterprise Linux
4.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

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:

* RHSA-2009:1024 introduced a flaw in the ptrace implementation on Itanium
systems. ptrace_check_attach() was not called during certain ptrace()
requests. Under certain circumstances, a local, unprivileged user could use
this flaw to call ptrace() on a process they do not own, giving them
control over that process. (CVE-2010-0729, Important)

* a flaw was found in the kernel's Unidirectional Lightweight Encapsulation
(ULE) implementation. A remote attacker could send a specially-crafted ISO
MPEG-2 Transport Stream (TS) frame to a target system, resulting in a
denial of service. (CVE-2010-1086, Important)

* a use-after-free flaw was found in tcp_rcv_state_process() in the
kernel's TCP/IP protocol suite implementation. If a system using IPv6 had
the IPV6_RECVPKTINFO option set on a listening socket, a remote attacker
could send an IPv6 packet to that system, causing a kernel panic.
(CVE-2010-1188, Important)

* a divide-by-zero flaw was found in azx_position_ok() in the Intel High
Definition Audio driver, snd-hda-intel. A local, unprivileged user could
trigger this flaw to cause a denial of service. (CVE-2010-1085, Moderate)

* an information leak flaw was found in the kernel's USB implementation.
Certain USB errors could result in an uninitialized kernel buffer being
sent to user-space. An attacker with physical access to a target system
could use this flaw to cause an information leak. (CVE-2010-1083, Low)

Red Hat would like to thank Ang Way Chuang for reporting CVE-2010-1086.

Bug fixes:

* a regression prevented the Broadcom BCM5761 network device from working
when in the first (top) PCI-E slot of Hewlett-Packard (HP) Z600 systems.
Note: The card worked in the 2nd or 3rd PCI-E slot. (BZ#567205)

* the Xen hypervisor supports 168 GB of RAM for 32-bit guests. The physical
address range was set incorrectly, however, causing 32-bit,
para-virtualized Red Hat Enterprise Linux 4.8 guests to crash when launched
on AMD64 or Intel 64 hosts that have more than 64 GB of RAM. (BZ#574392)

* RHSA-2009:1024 introduced a regression, causing diskdump to fail on
systems with certain adapters using the qla2xxx driver. (BZ#577234)

* a race condition caused TX to stop in a guest using the virtio_net
driver. (BZ#580089)

* on some systems, using the "arp_validate=3" bonding option caused both
links to show as "down" even though the arp_target was responding to ARP
requests sent by the bonding driver. (BZ#580842)

* in some circumstances, when a Red Hat Enterprise Linux client connected
to a re-booted Windows-based NFS server, server-side filehandle-to-inode
mapping changes caused a kernel panic. "bad_inode_ops" handling was changed
to prevent this. Note: filehandle-to-inode mapping changes may still cause
errors, but not panics. (BZ#582908)

* when installing a Red Hat Enterprise Linux 4 guest via PXE, hard-coded
fixed-size scatterlists could conflict with host requests, causing the
guest's kernel to panic. With this update, dynamically allocated
scatterlists are used, resolving this issue. (BZ#582911)

Enhancements:

* kernel support for connlimit. Note: iptables errata update RHBA-2010:0395
is also required for connlimit to work correctly. (BZ#563223)

* support for the Intel architectural performance monitoring subsystem
(arch_perfmon). On supported CPUs, arch_perfmon offers means to mark
performance events and options for configuring and counting these events.
(BZ#582913)

* kernel support for OProfile sampling of Intel microarchitecture (Nehalem)
CPUs. This update alone does not address OProfile support for such CPUs. A
future oprofile package update will allow OProfile to work on Intel Nehalem
CPUs. (BZ#582241)

Users should upgrade to these updated packages, which contain backported
patches to correct these issues and add these enhancements. The system must
be rebooted for this update to take effect.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

To install kernel packages manually, use "rpm -ivh [package]". Do not
use "rpm -Uvh" as that will remove the running kernel binaries from
your system. You may use "rpm -e" to remove old kernels after
determining that the new kernel functions properly on your system.
