RHSA-2007-0013: kernel

Vulnerability Assessment Summary
Check for the version of the kernel packages

Detailed Explanation for this Vulnerability Assessment

Updated kernel packages that fix a number of security issues as well as
other bugs are now available for Red Hat Enterprise Linux 2.1 (32 bit
architectures)

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

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

These new kernel packages contain fixes for the security issues described
below:

* a flaw in the ATM subsystem affecting systems with installed ATM hardware
and configured ATM support that permited a remote user to cause a denial of
service (panic) by accessing socket buffer memory after it has been freed
(CVE-2006-4997, Moderate)

* a flaw in the DVD handling of the CDROM driver that could be used
together with a custom built USB device to gain root rights
(CVE-2006-2935, Moderate)

In addition to the security issues described above, the following bugs are
also addressed:

* a potential overflow condition when reading /proc/devices
* uninitialized memory in cdrom_init() that can lead to a crash at install
time
* a potential page corruption bug in /proc/kcore
* a race condition when reading vmalloc()ed regions via /proc/kcore

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