Red Hat Security Advisory
Synopsis: Updated IA64 kernel packages address security vulnerabilities, bugfixes
Advisory ID: RHSA-2003:368-01

CVE Names: CAN-2003-0476 CAN-2003-0961
- - ---------------------------------------------------------------------
1. Topic:
Updated kernel packages that address several security vulnerabilites, fix a
number of bugs, and update various drivers are now available.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
3. Problem description:
The Linux kernel handles the basic functions of the operating system.
A flaw in bounds checking in the do_brk() function in the Linux kernel
versions 2.4.22 and previous can allow a local attacker to gain root
privileges. This issue is known to be exploitable; an exploit (for x86
architectures) has been seen in the wild that takes advantage of this
vulnerability. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0961 to this issue.
The execve system call in Linux 2.4.x records the file descriptor of the
executable process in the file table of the calling process, which allows
local users to gain read access to restricted file descriptors. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0476 to this issue.
A hangcheck timer (which is used to detect system hangs or pauses) has been
added.
In addition, a number of drivers have been updated:
- - - e1000 5.2.20-k1
- - - cmpci 5.64
- - - aic7xxx 6.2.36
- - - aic79xx 1.3.10
- - - ips 6.10.52
- - - cciss 2.4.50
- - - fusion 2.05.05+
All users of IA64 systems should upgrade to these errata packages, which
contain patches to the 2.4.18 kernel addressing these issues.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. 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.
If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
https://rhn.redhat.com/help/latest-up2date.pxt
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
107718 - lstat() claim files owned by users with uid>64k are owned by nfsnobody
106872 - RHEL 2.1 U3: Exposure of the EFI System Table pointers in a flat file (IPF)
101616 - RHELAS 2.1 Q3U IPF: Lazy FPH handling bug on IPF
96962 - ENSURE THAT HANGCHECK TIMER IS THERE IN THE IA64 TREE
87047 - raidstop --all option failing
106450 - Requesting updated acenic.o driver
106692 - RHEL 2.1 U3: Increase tx_queue_len parameter to 1000
90321 - fix /proc/$PID/cmdline issue
97690 - QU3 - IPF - export kernel symbol brw_kvec_async
71514 - Infinite recursion in SCSI mid layer

3. Problem description:
The Linux kernel handles the basic functions of the operating system.
The execve system call in Linux 2.4.x records the file descriptor of the

local users to gain read access to restricted file descriptors. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0476 to this issue.
A number of bugfixes are included, including important fixes for the ext3
file system and timer code.
New features include limited support for non-cached NFS file sytems, Serial
ATA (SATA) devices, and new alt-sysreq debugging options.
In addition, the following drivers have been updated:
- - - e100 2.3.30-k1
- - - e1000 5.2.20-k1
- - - fusion 2.05.05+

- - - aic79xxx 1.3.10
- - - megaraid 2 2.00.9
- - - cciss 2.4.49
All users are advised to upgrade to these erratum packages, which contain
backported patches addressing these issues.
4. Solution:
Release notes, driver notes, and driver disks for this update are available
at the following URL:
http://www.redhat.com/support/errata/rhel/
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
The procedure for upgrading the kernel manually is documented at:
http://www.redhat.com/support/docs/howto/kernel-upgrade/
Please read the directions for your architecture carefully before
proceeding with the kernel upgrade.
Please note that this update is also available via Red Hat Network. Many
people find this to be an easier way to apply updates. 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. Note that you need to select the kernel
explicitly on default configurations of up2date.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
99203 - NFS tcp client retransmission with large wsize.
74516 - NFS DATA CORRUPTION
