Red Hat Security Advisory

Synopsis: Low: gdm security and bug fix update
Advisory ID: RHSA-2010:0657-02
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0657.html
Issue date: 2010-08-26
CVE Names: CVE-2007-5079
=====================================================================

1. Summary:

An updated gdm package that fixes one security issue and one bug is now
available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having low
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 GNOME Display Manager (GDM) is a configurable re-implementation of XDM,
the X Display Manager. GDM allows you to log in to your system with the X
Window System running, and supports running several different X sessions on
your local machine at the same time.

A flaw was found in the way the gdm package was built. The gdm package was
missing TCP wrappers support on 64-bit platforms, which could result in an
administrator believing they had access restrictions enabled when they did
not. (CVE-2007-5079)

This update also fixes the following bug:

* sometimes the system would hang instead of properly shutting down when
a user chose "Shut down" from the login screen. (BZ#625818)

All users should upgrade to this updated package, which contains backported
patches to correct these issues. GDM must be restarted for this update to
take effect. Rebooting achieves this, but changing the runlevel from 5 to 3
and back to 5 also restarts GDM.

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

[RHSA-2010:0660-01] Important: kernel security and bug fix update

=====================================================================
Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2010:0660-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0660.html
Issue date: 2010-08-30
CVE Names: CVE-2010-2240 CVE-2010-2798
=====================================================================

1. Summary:

Updated kernel packages that fix two security issues and multiple bugs are
now available for Red Hat Enterprise Linux 5.3 Extended Update Support.

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. 5.3.z server) - i386, ia64, noarch, ppc, s390x, 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:

* when an application has a stack overflow, the stack could silently
overwrite another memory mapped area instead of a segmentation fault
occurring, which could cause an application to execute arbitrary code,
possibly leading to privilege escalation. It is known that the X Window
System server can be used to trigger this flaw. (CVE-2010-2240, Important)

* a miscalculation of the size of the free space of the initial directory
entry in a directory leaf block was found in the Linux kernel Global File
System 2 (GFS2) implementation. A local, unprivileged user with write
access to a GFS2-mounted file system could perform a rename operation on
that file system to trigger a NULL pointer dereference, possibly resulting
in a denial of service or privilege escalation. (CVE-2010-2798, Important)

Red Hat would like to thank the X.Org security team for reporting
CVE-2010-2240, with upstream acknowledging Rafal Wojtczuk as the original
reporter; and Grant Diffey of CenITex for reporting CVE-2010-2798.

This update also fixes the following bugs:

* the Red Hat Enterprise Linux 5.3 General Availability (GA) release
introduced a regression in iSCSI failover time. While there was heavy I/O
on the iSCSI layer, attempting to log out of an iSCSI connection at the
same time a network problem was occurring, such as a switch dying or a
cable being pulled out, resulted in iSCSI failover taking several minutes.
With this update, failover occurs as expected. (BZ#583898)

* a bug was found in the way the megaraid_sas driver (for SAS based RAID
controllers) handled physical disks and management IOCTLs. All physical
disks were exported to the disk layer, allowing an oops in
megasas_complete_cmd_dpc() when completing the IOCTL command if a timeout
occurred. One possible trigger for this bug was running "mkfs". This update
resolves this issue by updating the megaraid_sas driver to version 4.31.
(BZ#619362)

* this update upgrades the bnx2x driver to version 1.52.1-6, and the bnx2x
firmware to version 1.52.1-6, incorporating multiple bug fixes and
enhancements. These fixes include: A race condition on systems using the
bnx2x driver due to multiqueue being used to transmit data, but only a
single queue transmit ON/OFF scheme being used (only a single queue is
used with this update); a bug that could have led to a kernel panic when
using iSCSI offload; and a bug that caused a firmware crash, causing
network devices using the bnx2x driver to lose network connectivity. When
this firmware crash occurred, errors such as "timeout polling for state"
and "Stop leading failed!" were logged. A system reboot was required to
restore network connectivity. (BZ#620663, BZ#620668, BZ#620669, BZ#620665)

Users should upgrade to these updated packages, which contain backported
patches to correct these issues. 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.

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

583898 - REGRESSION: Fix iscsi failover time [rhel-5.3.z]
606611 - CVE-2010-2240 kernel: mm: keep a guard page below a grow-down stack segment

[RHSA-2010:0659-01] Moderate: httpd security and bug fix update

=====================================================================
Red Hat Security Advisory

Synopsis: Moderate: httpd security and bug fix update
Advisory ID: RHSA-2010:0659-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0659.html
Issue date: 2010-08-30
CVE Names: CVE-2010-1452 CVE-2010-2791
=====================================================================

1. Summary:

Updated httpd packages that fix two security issues and multiple bugs are
now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate
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:

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

3. Description:

The Apache HTTP Server is a popular web server.

A flaw was discovered in the way the mod_proxy module of the Apache HTTP
Server handled the timeouts of requests forwarded by a reverse proxy to the
back-end server. If the proxy was configured to reuse existing back-end
connections, it could return a response intended for another user under
certain timeout conditions, possibly leading to information disclosure.
(CVE-2010-2791)

A flaw was found in the way the mod_dav module of the Apache HTTP Server
handled certain requests. If a remote attacker were to send a carefully
crafted request to the server, it could cause the httpd child process to
crash. (CVE-2010-1452)

This update also fixes the following bugs:

* numerous issues in the INFLATE filter provided by mod_deflate. "Inflate
error -5 on flush" errors may have been logged. This update upgrades
mod_deflate to the newer upstream version from Apache HTTP Server 2.2.15.
(BZ#625435)

* the response would be corrupted if mod_filter applied the DEFLATE filter
to a resource requiring a subrequest with an internal redirect. (BZ#625451)

* the OID() function used in the mod_ssl "SSLRequire" directive did not
correctly evaluate extensions of an unknown type. (BZ#625452)

All httpd users should upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the updated
packages, the httpd daemon must be restarted for the 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

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

617523 - CVE-2010-2791 httpd: Reverse proxy sends wrong responses after time-outs
618189 - CVE-2010-1452 httpd mod_cache, mod_dav: DoS (httpd child process crash) by parsing URI structure with missing path segments
625435 - mod_deflate/mod_proxy generating 'Inflate error -5 on flush' errors
