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 privileges. This issue is rated as having moderate security impact (CVE-2005-1264).

A flaw in fragment forwarding was discovered that affected the netfilter subsystem for certain network interface cards. A remote attacker could send a set of bad fragments and cause a denial of service (system crash). Acenic and SunGEM network interfaces were the only adapters affected, which are in widespread use. (CVE-2005-0209)

A flaw in the futex functions was discovered affecting the Linux 2.6 kernel. A local user could use this flaw to cause a denial of service (system crash). (CVE-2005-0937)

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.
