RHSA-2005-420: kernel

Vulnerability Assessment Summary
Check for the version of the kernel packages

Detailed Explanation for this Vulnerability Assessment

Updated kernel packages are now available as part of ongoing support
and maintenance of Red Hat Enterprise Linux version 4. This is the
first regular update.

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

This is the first regular kernel update to Red Hat Enterprise Linux 4.

A flaw affecting the auditing code was discovered. On Itanium
architectures a local user could use this flaw to cause a denial of service
(crash). This issue is rated as having important security impact
(CVE-2005-0136).

A flaw was discovered in the servicing of a raw device ioctl. A local user
who has access to raw devices could use this flaw to write to kernel memory
and cause a denial of service or potentially gain rights. This issue
is rated as having moderate security impact (CVE-2005-1264).

New features introduced by this update include:
- Fixed TCP BIC congestion handling.
- Diskdump support for more controllers (megaraid, SATA)
- Device mapper multipath support
- AMD64 dual core support.
- Intel ICH7 hardware support.

There were many bug fixes in various parts of the kernel. The ongoing
effort to resolve these problems has resulted in a marked improvement
in the reliability and scalability of Red Hat Enterprise Linux 4.

ata_piix -------- 1.03
