"Updated kernel packages that fix various security issues and several
bugs are now available for Red Hat Enterprise Linux 5.

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

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

These updated packages fix the following security issues :

* a possible kernel memory leak was found in the Linux kernel Simple
Internet Transition (SIT) INET6 implementation. This could allow a
local unprivileged user to cause a denial of service. (CVE-2008-2136,
Important)

* a flaw was found in the Linux kernel setrlimit system call, when
setting RLIMIT_CPU to a certain value. This could allow a local
unprivileged user to bypass the CPU time limit. (CVE-2008-1294,
Moderate)

* multiple NULL pointer dereferences were found in various Linux
kernel network drivers. These drivers were missing checks for terminal
validity, which could allow privilege escalation. (CVE-2008-2812,
Moderate)

These updated packages fix the following bugs :

* the GNU libc stub resolver is a minimal resolver that works with
Domain Name System (DNS) servers to satisfy requests from applications
for names. The GNU libc stub resolver did not specify a source UDP
port, and therefore used predictable port numbers. This could have
made DNS spoofing attacks easier.

The Linux kernel has been updated to implement random UDP source ports
where none are specified by an application. This allows applications,
such as those using the GNU libc stub resolver, to use random UDP
source ports, helping to make DNS spoofing attacks harder.

* when using certain hardware, a bug in UART_BUG_TXEN may have caused
incorrect hardware detection, causing data flow to '/dev/ttyS1' to
hang.

* a 50-75% drop in NFS server rewrite performance, compared to Red Hat
Enterprise Linux 4.6, has been resolved.

* due a bug in the fast userspace mutex code, while one thread fetched
a pointer, another thread may have removed it, causing the first
thread to fetch the wrong pointer, possibly causing a system crash.

* on certain Hitachi hardware, removing the 'uhci_hcd' module caused a
kernel oops, and the following error :

BUG: warning at
arch/ia64/kernel/iosapic.c:1001/iosapic_unregister_intr()

Even after the 'uhci_hcd' module was reloaded, there was no access to
USB devices. As well, on systems that have legacy interrupts,
'acpi_unregister_gsi' incorrectly called 'iosapci_unregister_intr()',
causing warning messages to be logged.

* when a page was mapped with mmap(), and 'PROT_WRITE' was the only
'prot' argument, the first read of that page caused a segmentation
fault. If the page was read after it was written to, no fault
occurred. This was incompatible with the Red Hat Enterprise Linux 4
behavior.

* due to a NULL pointer dereference in powernowk8_init(), a panic may
have occurred.

* certain error conditions handled by the bonding sysfs interface
could have left rtnl_lock() unbalanced, either by locking and
returning without unlocking, or by unlocking when it did not lock,
possibly causing a 'kernel: RTNL: assertion failed at
net/core/fib_rules.c' error.

* the kernel currently expects a maximum of six Machine Check
Exception (MCE) banks to be exposed by a CPU. Certain CPUs have 7 or
more, which may have caused the MCE to be incorrectly reported.

* a race condition in UNIX domain sockets may have caused recv() to
return zero. For clusters, this may have caused unexpected failovers.

* msgrcv() frequently returned an incorrect 'ERESTARTNOHAND (514)'
error number.

* on certain Intel Itanium-based systems, when kdump was configured to
halt the system after a dump operation, after the 'System halted.'
output, the kernel continued to output endless 'soft lockup' messages.

Red Hat Enterprise Linux 5 users are advised to upgrade to these
updated packages, which contain backported patches to resolve these
issues."
