Three Red Hat Security Advisories:

1. RHSA-2006:0708-01 - Important: php security update

2. RHSA-2006:0688-01 - Important: php security update

3. RHSA-2006:0689-01 - Important: kernel security update

Detail
======

1. PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Web server.
An integer overflow was discovered in the PHP memory handling routines. If
a script can cause memory allocation based on untrusted user data, a remote
attacker sending a carefully crafted request could execute arbitrary code
as the 'apache' user. (CVE-2006-4812)

2. PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Web server.
An integer overflow was discovered in the PHP memory handling routines. If
a script can cause memory allocation based on untrusted user data, a remote
attacker sending a carefully crafted request could execute arbitrary code
as the 'apache' user. (CVE-2006-4812)

3. The Linux kernel handles the basic functions of the operating system.
These new kernel packages contain fixes for the security issues described.

Red Hat Security Advisory

Synopsis: Important: php security update
Advisory ID: RHSA-2006:0688-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2006-0688.html
Issue date: 2006-10-05
Updated on: 2006-10-05
Product: Red Hat Application Stack
CVE Names: CVE-2006-4020 CVE-2006-4482 CVE-2006-4484
CVE-2006-4485 CVE-2006-4486 CVE-2006-4812
- - ---------------------------------------------------------------------

1. Summary:

Updated PHP packages that fix multiple security issues are now available
for the Red Hat Application Stack.

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

2. Relevant releases/architectures:

Red Hat Application Stack v1 for Enterprise Linux AS (v.4) - i386, x86_64
Red Hat Application Stack v1 for Enterprise Linux ES (v.4) - i386, x86_64

3. Problem description:

PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Web server.

An integer overflow was discovered in the PHP memory handling routines. If
a script can cause memory allocation based on untrusted user data, a remote
attacker sending a carefully crafted request could execute arbitrary code
as the 'apache' user. (CVE-2006-4812)

A buffer overflow was discovered in the PHP sscanf() function. If a script
used the sscanf() function with positional arguments in the format string,
a remote attacker sending a carefully crafted request could execute
arbitrary code as the 'apache' user. (CVE-2006-4020)

An integer overflow was discovered in the PHP wordwrap() and str_repeat()
functions. If a script running on a 64-bit server used either of these
functions on untrusted user data, a remote attacker sending a carefully
crafted request might be able to cause a heap overflow. (CVE-2006-4482)

A buffer overflow was discovered in the PHP gd extension. If a script was
set up to process GIF images from untrusted sources using the gd extension,
a remote attacker could cause a heap overflow. (CVE-2006-4484)

A buffer overread was discovered in the PHP stripos() function. If a
script used the stripos() function with untrusted user data, PHP may read
past the end of a buffer, which could allow a denial of service attack by a
remote user. (CVE-2006-4485)

An integer overflow was discovered in the PHP memory allocation handling.
On 64-bit platforms, the "memory_limit" setting was not enforced correctly,
which could allow a denial of service attack by a remote user. (CVE-2006-4486)

These packages also contain a fix for a bug where certain input strings to
the metaphone() function could cause memory corruption.

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

4. Solution:

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

This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate

Red Hat Security Advisory

Synopsis: Important: kernel security update
Advisory ID: RHSA-2006:0689-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2006-0689.html
Issue date: 2006-10-05
Updated on: 2006-10-05
Product: Red Hat Enterprise Linux
Keywords: nahant kernel update
Obsoletes: RHSA-2006:0617
CVE Names: CVE-2005-4811 CVE-2006-0039 CVE-2006-2071

- - ---------------------------------------------------------------------

1. Summary:

Updated kernel packages that fix several security issues in the Red Hat
Enterprise Linux 4 kernel are now available.

This security advisory 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, 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. Problem description:

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the security issues described
below:

* a flaw in the SCTP support that allowed a local user to cause a denial of
service (crash) with a specific SO_LINGER value. (CVE-2006-4535, Important)

* a flaw in the hugepage table support that allowed a local user to cause a
denial of service (crash). (CVE-2005-4811, Important)

* a flaw in the mprotect system call that allowed setting write permission
for a read-only attachment of shared memory. (CVE-2006-2071, Moderate)

* a flaw in HID0[31] (en_attn) register handling on PowerPC 970 systems
that allowed a local user to cause a denial of service. (crash)
(CVE-2006-4093, Moderate)

* a flaw in the perfmon support of Itanium systems that allowed a local
user to cause a denial of service by consuming all file descriptors.
(CVE-2006-3741, Moderate)

* a flaw in the ATM subsystem. On systems with installed ATM hardware and
configured ATM support, a remote user could cause a denial of service
(panic) by accessing socket buffers memory after freeing them.
(CVE-2006-4997, Moderate)

* a flaw in the DVB subsystem. On systems with installed DVB hardware and
configured DVB support, a remote user could cause a denial of service
(panic) by sending a ULE SNDU packet with length of 0. (CVE-2006-4623, Low)

* an information leak in the network subsystem that possibly allowed a
local user to read sensitive data from kernel memory. (CVE-2006-0039, Low)

In addition, two bugfixes for the IPW-2200 wireless driver were included.
The first one ensures that wireless management applications correctly
identify IPW-2200 controlled devices, while the second fix ensures that
DHCP requests using the IPW-2200 operate correctly.

Red Hat would like to thank Olof Johansson, Stephane Eranian and Solar
Designer for reporting issues fixed in this erratum.

All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels
to the packages associated with their machine architectures and
configurations as listed in this erratum.

4. Solution:

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

This update is available via Red Hat Network. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

165345 - CVE-2005-4811 Hugepage crash on failing mmap()
190073 - CVE-2006-2071 mprotect gives write permission to a readonly attachment
191698 - CVE-2006-0039 netfilter do_add_counters race
198820 - IPW2200 /proc/net/wireless file fields are empty
201684 - CVE-2006-4093 Local DoS through uncleared HID0[31]
203421 - Grabbing DHCP address via wireless not always successful
204360 - CVE-2006-3741 sys_perfmonctl() file descriptor reference count issue
204460 - CVE-2006-4535 Regression with fix for SCTP abort issue
204912 - CVE-2006-4623 Wrong handling of DVB ULE SNDU with length of 0
