6.4 - RHSA-2005:663

Problem Description:

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

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

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

This is the sixth regular kernel update to Red Hat Enterprise Linux 3.

New features introduced by this update include:

- diskdump support on HP Smart Array devices
- netconsole/netdump support over bonded interfaces
- new chipset and device support via PCI table updates
- support for new "oom-kill" and "kscand_work_percent" sysctls
- support for dual core processors and ACPI Power Management timers on
AMD64 and Intel EM64T systems

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 3.

There were numerous driver updates and security fixes (elaborated below). Other key areas affected by fixes in this update include kswapd, inode handling, the SATA subsystem, diskdump handling, ptrace() syscall support, and signal handling.

The following device drivers have been upgraded to new versions:

3w-9xxx ---- 2.24.03.008RH
cciss ------ 2.4.58.RH1
e100 ------- 3.4.8-k2
e1000 ------ 6.0.54-k2
emulex ----- 7.3.2
fusion ----- 2.06.16i.01
iscsi ------ 3.6.2.1
ipmi ------- 35.4
lpfcdfc ---- 1.2.1
qlogic ----- 7.05.00-RH1
tg3 -------- 3.27RH

The following security bugs were fixed in this update:

- a flaw in syscall argument checking on Itanium systems that allowed
a local user to cause a denial of service (crash) (CAN-2005-0136)

- a flaw in stack expansion that allowed a local user of mlockall()
to cause a denial of service (memory exhaustion) (CAN-2005-0179)

- a small memory leak in network packet defragmenting that allowed a
remote user to cause a denial of service (memory exhaustion) on
systems using netfilter (CAN-2005-0210)

- flaws in ptrace() syscall handling on AMD64 and Intel EM64T systems
that allowed a local user to cause a denial of service (crash)
(CAN-2005-0756, CAN-2005-1762, CAN-2005-2553)

- flaws in ISO-9660 file system handling that allowed the mounting of
an invalid image on a CD-ROM to cause a denial of service (crash)
or potentially execute arbitrary code (CAN-2005-0815)

- a flaw in ptrace() syscall handling on Itanium systems that allowed
a local user to cause a denial of service (crash) (CAN-2005-1761)

- a flaw in the alternate stack switching on AMD64 and Intel EM64T
systems that allowed a local user to cause a denial of service
(crash) (CAN-2005-1767)

- race conditions in the ia32-compat support for exec() syscalls on
AMD64, Intel EM64T, and Itanium systems that could allow a local
user to cause a denial of service (crash) (CAN-2005-1768)

- flaws in IPSEC network handling that allowed a local user to cause
a denial of service or potentially gain privileges (CAN-2005-2456,
CAN-2005-2555)

- a flaw in sendmsg() syscall handling on 64-bit systems that allowed
a local user to cause a denial of service or potentially gain
privileges (CAN-2005-2490)

- flaws in unsupported modules that allowed denial-of-service attacks
(crashes) or local privilege escalations on systems using the drm,
coda, or moxa modules (CAN-2004-1056, CAN-2005-0124, CAN-2005-0504)

- potential leaks of kernel data from jfs and ext2 file system handling
(CAN-2004-0181, CAN-2005-0400)

Note: The kernel-unsupported package contains various drivers and modules that are unsupported and therefore might contain security problems that have not been addressed.

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.

4. Solution:

Before applying this update, make sure that all previously released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:

up2date
