Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2007:0099-02
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0099.html
Issue date: 2007-03-14
Updated on: 2007-03-14
Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-0005 CVE-2007-0006 CVE-2007-0958
- ---------------------------------------------------------------------

1. Summary:

Updated kernel packages that fix security issues and bugs in the Red Hat
Enterprise Linux 5 kernel are now available.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64

3. Problem description:

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

These new kernel packages contain fixes for the following security issues:

* a flaw in the key serial number collision avoidance algorithm of the
keyctl subsystem that allowed a local user to cause a denial of service
(CVE-2007-0006, Important)

* a flaw in the Omnikey CardMan 4040 driver that allowed a local user to
execute arbitrary code with kernel privileges. In order to exploit this
issue, the Omnikey CardMan 4040 PCMCIA card must be present and the local
user must have access rights to the character device created by the driver.
(CVE-2007-0005, Moderate)

* a flaw in the core-dump handling that allowed a local user to create core
dumps from unreadable binaries via PT_INTERP. (CVE-2007-0958, Low)

In addition to the security issues described above, a fix for a kernel
panic in the powernow-k8 module, and a fix for a kernel panic when booting
the Xen domain-0 on system with large memory installations have been included.

Red Hat would like to thank Daniel Roethlisberger for reporting an issue
fixed in this erratum.

Red Hat Enterprise Linux 5 users are advised to upgrade their kernels to
the packages associated with their machine architecture and configurations
as listed in this erratum.

229883 - CVE-2007-0006 Key serial number collision problem
229884 - CVE-2007-0005 Buffer Overflow in Omnikey CardMan 4040 cmx driver
