RHEL 4 : kernel (RHSA-2007:0774)

This script is Copyright (C) 2007-2016 Tenable Network Security, Inc.

Synopsis :

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

Description :

Updated kernel packages that fix several security issues and bugs in
the Red Hat Enterprise Linux 4 kernel are now available.

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

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 ISDN CAPI subsystem that allowed a remote user to
cause a denial of service or potential remote access. Exploitation
would require the attacker to be able to send arbitrary frames over
the ISDN network to the victim's machine. (CVE-2007-1217, Moderate)

* a flaw in the perfmon subsystem on ia64 platforms that allowed a
local user to cause a denial of service. (CVE-2006-0558, Moderate)

In addition, the following bugs were addressed :

* a panic after reloading of the LSI Fusion driver.

* a vm performance problem was corrected by balancing inactive page

* added a nodirplus option to address NFSv3 performance issues with
large directories.

* changed the personality handling to disallow personality changes of
setuid and setgid binaries. This ensures they keep any randomization
and Exec-shield protection.

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.
