[RHSA-2011:1496-01] Important: bind security update
=====================================================================
Red Hat Security Advisory

Synopsis: Important: bind security update
Advisory ID: RHSA-2011:1496-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1496.html
Issue date: 2011-11-29
CVE Names: CVE-2011-4313
=====================================================================

1. Summary:

Updated bind packages that fix one security issue are now available for
Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

2. Relevant releases/architectures:

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

3. Description:

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
library (routines for applications to use when interfacing with DNS); and
tools for verifying that the DNS server is operating correctly.

A flaw was discovered in the way BIND handled certain DNS queries, which
caused it to cache an invalid record. A remote attacker could use this
flaw to send repeated queries for this invalid record, causing the
resolvers to exit unexpectedly due to a failed assertion. (CVE-2011-4313)

Users of bind are advised to upgrade to these updated packages, which
resolve this issue. After installing the update, the BIND daemon (named)
will be restarted automatically.

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
https://access.redhat.com/kb/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

754398 - CVE-2011-4313 bind: Remote denial of service against recursive servers via logging negative cache entry

[RHSA-2011:1479-01] Important: kernel security, bug fix, and enhancement update
=====================================================================
Red Hat Security Advisory

Synopsis: Important: kernel security, bug fix, and enhancement update
Advisory ID: RHSA-2011:1479-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-1479.html
Issue date: 2011-11-29
CVE Names: CVE-2011-1162 CVE-2011-1898 CVE-2011-2203
CVE-2011-2494 CVE-2011-3363 CVE-2011-4110
=====================================================================

1. Summary:

Updated kernel packages that fix multiple security issues, several bugs,
and add one enhancement are now available for Red Hat Enterprise Linux 5.

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 (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64

3. Description:

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

This update fixes the following security issues:

* Using PCI passthrough without interrupt remapping support allowed Xen
hypervisor guests to generate MSI interrupts and thus potentially inject
traps. A privileged guest user could use this flaw to crash the host or
possibly escalate their privileges on the host. The fix for this issue can
prevent PCI passthrough working and guests starting. Refer to Red Hat
Bugzilla bug 715555 for details. (CVE-2011-1898, Important)

* A flaw was found in the way CIFS (Common Internet File System) shares
with DFS referrals at their root were handled. An attacker on the local
network who is able to deploy a malicious CIFS server could create a CIFS
network share that, when mounted, would cause the client system to crash.
(CVE-2011-3363, Moderate)

* A NULL pointer dereference flaw was found in the way the Linux kernel's
key management facility handled user-defined key types. A local,
unprivileged user could use the keyctl utility to cause a denial of
service. (CVE-2011-4110, Moderate)

* A flaw in the way memory containing security-related data was handled in
tpm_read() could allow a local, unprivileged user to read the results of a
previously run TPM command. (CVE-2011-1162, Low)

* A NULL pointer dereference flaw was found in the Linux kernel's HFS file
system implementation. A local attacker could use this flaw to cause a
denial of service by mounting a disk that contains a specially-crafted HFS
file system with a corrupted MDB extent record. (CVE-2011-2203, Low)

* The I/O statistics from the taskstats subsystem could be read without
any restrictions. A local, unprivileged user could use this flaw to gather
confidential information, such as the length of a password used in a
process. (CVE-2011-2494, Low)

Red Hat would like to thank Yogesh Sharma for reporting CVE-2011-3363;
Peter Huewe for reporting CVE-2011-1162; Clement Lecigne for reporting
CVE-2011-2203; and Vasiliy Kulikov of Openwall for reporting CVE-2011-2494.

This update also fixes several bugs and adds one enhancement. Documentation
for these changes will be available shortly from the Technical Notes
document linked to in the References section.

Users should upgrade to these updated packages, which contain backported
patches to correct these issues, and fix the bugs and add the enhancement
noted in the Technical Notes. 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
https://access.redhat.com/kb/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.

5. Bugs fixed (http://bugzilla.redhat.com/):

712774 - CVE-2011-2203 kernel: hfs_find_init() sb->ext_tree NULL pointer dereference
715555 - CVE-2011-1898 virt: VT-d (PCI passthrough) MSI trap injection
716842 - CVE-2011-2494 kernel: taskstats io infoleak
732629 - CVE-2011-1162 kernel: tpm: infoleak
738291 - CVE-2011-3363 kernel: cifs: always do is_path_accessible check in cifs_mount
741273 - Non-responsive scsi target leads to excessive scsi recovery and dm-mp failover time [rhel-5.7.z]
745726 - Host crash when pass-through fails [rhel-5.7.z]
751297 - CVE-2011-4110 kernel: keys: NULL pointer deref in the user-defined key type
