CVE Names: CAN-2004-1072
----------------------------------------------------------------------

1. Summary:

An updated ia32el package that fixes several bugs is now available.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 Extras - ia64
Red Hat Enterprise Linux ES version 3 Extras - ia64
Red Hat Enterprise Linux WS version 3 Extras - ia64



3. Problem description:

The ia32el package contains IA-32 Execution Layer platform which allows emulation of IA-32 binaries on IA-64.

A flaw was found in the binfmt_elf loader of the Linux kernel which also affects the IA-32 Execution Layer. A local user could create an interpreter name string that is not NULL terminated, leading to a denial of service (crash). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-1072 to this issue.

This update also addresses the following issues:

- -- Fixed execve to invoke ia32 interpreter
- -- Credential fixes
- -- Fixed a bug causing ibm-jvm to fail
- -- Other minor bug fixes

Please refer to the package release notes for detailed information about these changes.

All users of ia32el should upgrade to this updated package, which resolves 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.
