RHEL 3 : kernel (RHSA-2004:017)

Synopsis :

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

Description :

Updated kernel packages are now available as part of ongoing support
and maintenance of Red Hat Enterprise Linux version 3. This is the
first regular update.

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

This is the first regular kernel update for Red Hat Enterprise Linux
version 3. It contains a new critical security fix, many other bug
fixes, several device driver updates, and numerous performance and
scalability enhancements.

On AMD64 systems, a fix was made to the eflags checking in 32-bit
ptrace emulation that could have allowed local users to elevate their
privileges. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0001 to this issue.

Other bug fixes were made in the following kernel areas: VM, NPTL,
IPC, kernel timer, ext3, NFS, netdump, SCSI, ACPI, several device
drivers, and machine-dependent support for the x86_64, ppc64, and s390
architectures.

The VM subsystem was improved to better handle extreme loads and
resource contention (such as might occur during heavy database
application usage). This has resulted in a significantly reduced
possibility of hangs, OOM kills, and low-mem exhaustion.

Several NPTL fixes were made to resolve POSIX compliance issues
concerning process IDs and thread IDs. A section in the Release Notes
elaborates on a related issue with file record locking in
multi-threaded applications.

AMD64 kernels are now configured with NUMA support, S390 kernels now
have CONFIG_BLK_STATS enabled, and DMA capability was restored in the
IA64 agpgart driver.

The following drivers have been upgraded to new versions :

cmpci ------ 6.36 e100 ------- 2.3.30-k1 e1000 ------ 5.2.20-k1 ips
-------- 6.10.52 megaraid --- v1.18k megaraid2 -- v2.00.9

All Red Hat Enterprise Linux 3 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum.
