kernel security update

Advisory:	RHSA-2004:418-05
Type:	Security Advisory
Severity:	Important
Issued on:	2004-08-03
Last updated on:	2004-08-03
Affected Products:	Red Hat Enterprise Linux AS (v. 2.1) Red Hat Enterprise Linux ES (v. 2.1) Red Hat Enterprise Linux WS (v. 2.1)
CVEs (cve.mitre.org):	CVE-2004-0415 CVE-2004-0535 CVE-2004-0587

Details

Updated kernel packages that fix potential information leaks and a
incorrect driver permission for Red Hat Enterprise Linux 2.1 are now available.

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

Paul Starzetz discovered flaws in the Linux kernel when handling file
offset pointers. These consist of invalid conversions of 64 to 32-bit file
offset pointers and possible race conditions. A local unprivileged user
could make use of these flaws to access large portions of kernel memory.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-0415 to this issue.

These packages contain a patch written by Al Viro to correct these flaws.
Red Hat would like to thank iSEC Security Research for disclosing this
issue and a number of vendor-sec participants for reviewing and working on
the patch to this issue.

In addition, these packages correct two minor issues:

An bug in the e1000 network driver. This bug could be used by local users
to leak small amounts of kernel memory (CAN-2004-0535).

Inappropriate permissions on /proc/scsi/qla2300/HbaApiNode (CAN-2004-0587).

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels
to these erratum packages which contain backported patches to correct these
issues.

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
