- --------------------------------------------------------------------- Red Hat Security Advisory
Synopsis: Moderate: kernel security update Advisory ID: RHSA-2007:0013-01 Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0013.html Issue date: 2007-01-17 Updated on: 2007-01-17 Product: Red Hat Enterprise Linux CVE Names: CVE-2006-2935 CVE-2006-4997 - ---------------------------------------------------------------------
1. Summary:
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.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386
3. Problem description:
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 allowed 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 privileges (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.
4. Solution:
Before applying this update, make sure all previously released errata relevant to your system have been applied.
This update is available via Red Hat Network. 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.
5. Bug IDs fixed (http://bugzilla.redhat.com/):
102095 - Panic occurs at the time of installation. 147666 - Memory corruption when reading /proc/kcore 156029 - kernel may oops if more than 4k worth of string data returned in /proc/devices 197673 - CVE-2006-2935 Possible buffer overflow in DVD handling 207306 - CVE-2006-4997 IP over ATM clip_mkip dereference freed pointer 213567 - Access to unmapped vmalloc pages when reading proc/kcore
