"Updated kernel packages that fix several security issues 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.

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

This advisory includes fixes for several security issues :

iSEC Security Research discovered multiple vulnerabilities in the IGMP
functionality. These flaws could allow a local user to cause a denial
of service (crash) or potentially gain privileges. Where multicast
applications are being used on a system, these flaws may also allow
remote users to cause a denial of service. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1137 to this issue.

iSEC Security Research discovered a flaw in the page fault handler
code that could lead to local users gaining elevated (root) privileges
on multiprocessor machines. (CVE-2005-0001)

iSEC Security Research discovered a VMA handling flaw in the uselib(2)
system call of the Linux kernel. A local user could make use of this
flaw to gain elevated (root) privileges. (CVE-2004-1235)

A flaw affecting the OUTS instruction on the AMD64 and Intel EM64T
architecture was discovered. A local user could use this flaw to write
to privileged IO ports. (CVE-2005-0204)

The Direct Rendering Manager (DRM) driver in Linux kernel 2.6 does not
properly check the DMA lock, which could allow remote attackers or
local users to cause a denial of service (X Server crash) or possibly
modify the video output. (CVE-2004-1056)

OGAWA Hirofumi discovered incorrect tables sizes being used in the
filesystem Native Language Support ASCII translation table. This could
lead to a denial of service (system crash). (CVE-2005-0177)

Michael Kerrisk discovered a flaw in the 2.6.9 kernel which allows
users to unlock arbitrary shared memory segments. This flaw could lead
to applications not behaving as expected. (CVE-2005-0176)

Improvements in the POSIX signal and tty standards compliance exposed
a race condition. This flaw can be triggered accidentally by threaded
applications or deliberately by a malicious user and can result in a
denial of service (crash) or in occasional cases give access to a
small random chunk of kernel memory. (CVE-2005-0178)

The PaX team discovered a flaw in mlockall introduced in the 2.6.9
kernel. An unprivileged user could use this flaw to cause a denial of
service (CPU and memory consumption or crash). (CVE-2005-0179)

Brad Spengler discovered multiple flaws in sg_scsi_ioctl in the 2.6
kernel. An unprivileged user may be able to use this flaw to cause a
denial of service (crash) or possibly other actions. (CVE-2005-0180)

Kirill Korotaev discovered a missing access check regression in the
Red Hat Enterprise Linux 4 kernel 4GB/4GB split patch. On systems
using the hugemem kernel, a local unprivileged user could use this
flaw to cause a denial of service (crash). (CVE-2005-0090)

A flaw in the Red Hat Enterprise Linux 4 kernel 4GB/4GB split patch
can allow syscalls to read and write arbitrary kernel memory. On
systems using the hugemem kernel, a local unprivileged user could use
this flaw to gain privileges. (CVE-2005-0091)

An additional flaw in the Red Hat Enterprise Linux 4 kernel 4GB/4GB
split patch was discovered. On x86 systems using the hugemem kernel, a
local unprivileged user may be able to use this flaw to cause a denial
of service (crash). (CVE-2005-0092)

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."

"CAN-2004-0176 :

Michael Kerrisk noticed an insufficient permission checking in the
shmctl() function. Any process was permitted to lock/unlock any System
V shared memory segment that fell within the the RLIMIT_MEMLOCK limit
(that is the maximum size of shared memory that unprivileged users can
acquire). This allowed am unprivileged user process to unlock locked
memory of other processes, thereby allowing them to be swapped out.
Usually locked shared memory is used to store passphrases and other
sensitive content which must not be written to the swap space (where
it could be read out even after a reboot).

CAN-2005-0177 :

OGAWA Hirofumi noticed that the table sizes in nls_ascii.c were
incorrectly set to 128 instead of 256. This caused a buffer overflow
in some cases which could be exploited to crash the kernel.

CAN-2005-0178 :

A race condition was found in the terminal handling of the 'setsid()'
function, which is used to start new process sessions.

http://oss.sgi.com/archives/netdev/2005-01/msg01036.html :

David Coulson noticed a design flaw in the netfilter/iptables module.
By sending specially crafted packets, a remote attacker could exploit
this to crash the kernel or to bypass firewall rules.

Fixing this vulnerability required a change in the
Application Binary Interface (ABI) of the kernel. This means
that third-party user installed modules might not work any
more with the new kernel, so this fixed kernel has a new ABI
version number. You have to recompile and reinstall all
third-party modules.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

"Updated kernel packages that fix several security issues in the Red
Hat Enterprise Linux 3 kernel are now available.

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

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

These new kernel packages contain fixes for the three security issues
described below as well as an important fix for a problem that could
lead to data corruption on x86-architecture SMP systems with greater
than 4GB of memory through heavy usage of multi-threaded applications.

A flaw between execve() syscall handling and core dumping of
ELF-format executables allowed local unprivileged users to cause a
denial of service (system crash) or possibly gain privileges. The
Common Vulnerabilities and Exposures project has assigned the name
CVE-2005-1263 to this issue.

A flaw in shared memory locking allowed local unprivileged users to
lock and unlock regions of shared memory segments they did not own
(CVE-2005-0176).

A flaw in the locking of SysV IPC shared memory regions allowed local
unprivileged users to bypass their RLIMIT_MEMLOCK resource limit
(CVE-2004-0491).

Note: The kernel-unsupported package contains various drivers and
modules that are unsupported and therefore might contain security
problems that have not been addressed.

All Red Hat Enterprise Linux 3 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum.

Please also consult the RHEL3 Update 5 advisory RHSA-2005:294 for the
complete list of features added and bugs fixed in U5, which was
released only a week prior to this security update."
