RHSA-2002-227: kernel Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the kernel packages

Detailed Explanation for this Vulnerability Test

This kernel update for Red Hat Linux Advanced Server 2.1 addresses some
security issues and provides minor bug fixes.

The Linux kernel handles the basic functions of the operating system. A
number of vulnerabilities were found in the Red Hat Linux Advanced Server
kernel. These vulnerabilities could allow a local user to obtain elevated
(root) rights.

The vulnerabilities existed in a number of drivers, including
stradis, rio500, se401, apm, usbserial, and usbvideo.

Additionally, a number of bugs have been fixed, and some small feature
enhancements have been added.

- Failed READA requests could be interpreted as I/O errors under high
load on SMP
this has been fixed.

- In rare cases, TLB entries could be corrupted on SMP Pentium IV
this potential for corruption has been fixed. Third-party modules
will need to be recompiled to take advantage of these fixes.

- The latest tg3 driver fixes have been included
the tg3 driver
now supports more hardware.

- A mechanism is provided to specify the location of core files and to
set the name pattern to include the UID, program, hostname, and PID of
the process that caused the core dump.

A number of SCSI fixes have also been included:

- Configure sparse LUNs in the qla2200 driver
- Clean up erroneous accounting data as seen by /proc/partitions and iostat
- Allow up to 128 scsi disks
- Do not start logical units that require manual intervention, avoiding
unnecessary startup delays
- Improve SCSI layer throughput by properly clustering DMA requests

All users of Red Hat Linux Advanced Server are advised to upgrade to the
errata packages.
