Enterprise Linux 3 are now available.

2. Relevant releases/architectures:

Red Hat Enterprise Linux WS version 3 - athlon, i386, i686, ia32e, ia64, x86_64

3. Problem description:

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

This update includes fixes for several security issues:

A missing serialization flaw in unix_dgram_recvmsg was discovered that
affects kernels prior to 2.4.28.  A local user could potentially make
use of a race condition in order to gain privileges.  The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-1068 to this issue.

Paul Starzetz of iSEC discovered various flaws in the ELF binary
loader affecting kernels prior to 2.4.28.  A local user could use thse
flaws to gain read access to executable-only binaries or possibly gain
privileges. (CAN-2004-1070, CAN-2004-1071, CAN-2004-1072, CAN-2004-1073)

A flaw when setting up TSS limits was discovered that affects AMD AMD64
and Intel EM64T architecture kernels prior to 2.4.23.  A local user could
use this flaw to cause a denial of service (crash) or possibly gain
privileges.  (CAN-2004-0812)

An integer overflow flaw was discovered in the ubsec_keysetup function
in the Broadcom 5820 cryptonet driver.  On systems using this driver,
a local user could cause a denial of service (crash) or possibly gain
elevated privileges.  (CAN-2004-0619)

Stefan Esser discovered various flaws including buffer overflows in
the smbfs driver affecting kernels prior to 2.4.28.  A local user may be
able to cause a denial of service (crash) or possibly gain privileges.
In order to exploit these flaws the user would require control of
a connected Samba server.  (CAN-2004-0883, CAN-2004-0949)

SGI discovered a bug in the elf loader that affects kernels prior to
2.4.25 which could be triggered by a malformed binary.  On
architectures other than x86, a local user could create a malicious
binary which could cause a denial of service (crash).  (CAN-2004-0136)

Conectiva discovered flaws in certain USB drivers affecting kernels
prior to 2.4.27 which used the copy_to_user function on uninitialized
structures.  These flaws could allow local users to read small amounts
of kernel memory.  (CAN-2004-0685)

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.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  Use Red Hat
Network to download and update your packages.  To launch the Red Hat
Update Agent, use the following command:

    up2date

For information on how to install packages manually, refer to the
following Web page for the System Administration or Customization
guide specific to your system:
