The remote Red Hat host is missing one or more security updates.
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.
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.
