Security Advisory kernel security update

Advisory: RHSA-2006:0574-8
Type: Security Advisory
Severity: Important
Issued on: 2006-07-07
Last updated on: 2006-07-07
Affected Products: Red Hat Desktop (v. 4)
Red Hat Enterprise Linux AS (v. 4)

Red Hat Enterprise Linux WS (v. 4)
CVEs (cve.mitre.org): CVE-2006-2451

Details

Updated kernel packages that fix a privilege escalation security issue in
the Red Hat Enterprise Linux 4 kernel are now available.

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

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

During security research, Red Hat discovered a behavioral flaw in core dump
handling. A local user could create a program that would cause a core file
to be dumped into a directory they would not normally have permissions to
write to. This could lead to a denial of service (disk consumption), or
allow the local user to gain root privileges. (CVE-2006-2451)

Prior to applying this update, users can remove the ability to escalate
privileges using this flaw by configuring core files to dump to an absolute
location. By default, core files are created in the working directory of
the faulting application, but this can be overridden by specifying an
absolute location for core files in /proc/sys/kernel/core_pattern. To
avoid a potential denial of service, a separate partition for the core
files should be used.

All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels
to the packages associated with their machine architectures and
configurations as listed in this erratum.


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.
