RedHat RHSA-2003:088-01: updated kernel 2.2 packages

by Nikola Strahija on March 22nd, 2003 A bug in the kernel module loader code allows remote attackers to obtain information from previous packets or kernel memory by using malformed packets.

Red Hat Security Advisory

Synopsis: New kernel 2.2 packages fix vulnerabilities
Advisory ID: RHSA-2003:088-01
Issue date: 2003-03-20
Updated on: 2003-03-20
Product: Red Hat Linux
Keywords: ethernet frame padding /proc/pid/mem
Cross references:
Obsoletes: RHSA-2002:264
CVE Names: CAN-2003-0001 CAN-2003-1380 CAN-2003-0127

1. Topic:

Updated kernel packages for Red Hat Linux 6.2 and 7.0 are now available
that fix several security vulnerabilities.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - i386, i586, i686
Red Hat Linux 7.0 - i386, i586, i686

3. Problem description:

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

A bug in the kernel module loader code allows a local user to gain root
privileges. The Common Vulnerabilities and Exposures project
( has assigned the name CAN-2003-0127 to this issue.

Multiple ethernet Network Interface Card (NIC) device drivers do not pad
frames with null bytes, which allows remote attackers to obtain information
from previous packets or kernel memory by using malformed packets. The
Common Vulnerabilities and Exposures project ( has assigned
the name CAN-2003-0001 to this issue.

The Linux 2.2 kernel allows local users to cause a denial of service
(crash) by using the mmap() function with a PROT_READ parameter to access
non-readable memory pages through the /proc/pid/mem interface. The
Common Vulnerabilities and Exposures project ( has assigned
the name CAN-2002-1380 to this issue.

All users of Red Hat Linux 6.2 and 7 should upgrade to these errata
packages, which contain version 2.2.24 of the Linux kernel with patches and
are not vulnerable to these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

The procedure for upgrading the kernel is documented at:

Please read the directions for your architecture carefully before
proceeding with the kernel upgrade.

Please note that this update is also available via Red Hat Network. Many
people find this to be an easier way to apply updates. To use Red Hat
Network, launch the Red Hat Update Agent with the following command:


This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system. Note that you need to select the kernel
explicitly on default configurations of up2date.

5. RPMs required:

Red Hat Linux 6.2:





Red Hat Linux 7.0:
