Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2009:1671-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1671.html
Issue date: 2009-12-15
CVE Names: CVE-2009-2910 CVE-2009-3613 CVE-2009-3620
CVE-2009-3621
=====================================================================

1. Summary:

Updated kernel packages that fix multiple security issues and several bugs
are now available for Red Hat Enterprise Linux 4.

This update 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 4 - i386, ia64, noarch, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, noarch, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, noarch, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, noarch, x86_64

3. Description:

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

This update fixes the following security issues:

* a flaw was found in the Realtek r8169 Ethernet driver in the Linux
kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU
space exhaustion and a system crash. An attacker on the local network could
trigger this flaw by using jumbo frames for large amounts of network
traffic. (CVE-2009-3613, Important)

* NULL pointer dereference flaws were found in the r128 driver in the Linux
kernel. Checks to test if the Concurrent Command Engine state was
initialized were missing in private IOCTL functions. An attacker could use
these flaws to cause a local denial of service or escalate their
privileges. (CVE-2009-3620, Important)

* an information leak was found in the Linux kernel. On AMD64 systems,
32-bit processes could access and read certain 64-bit registers by
temporarily switching themselves to 64-bit mode. (CVE-2009-2910, Moderate)

* the unix_stream_connect() function in the Linux kernel did not check if a
UNIX domain socket was in the shutdown state. This could lead to a
deadlock. A local, unprivileged user could use this flaw to cause a denial
of service. (CVE-2009-3621, Moderate)

This update also fixes the following bugs:

* an iptables rule with the recent module and a hit count value greater
than the ip_pkt_list_tot parameter (the default is 20), did not have any
effect over packets, as the hit count could not be reached. (BZ#529306)

* in environments that use dual-controller storage devices with the cciss
driver, Device-Mapper Multipath maps could not be detected and configured,
due to the cciss driver not exporting the bus attribute via sysfs. This
attribute is now exported. (BZ#529309)

* the kernel crashed with a divide error when a certain joystick was
attached. (BZ#532027)

* a bug in the mptctl_do_mpt_command() function in the mpt driver may have
resulted in crashes during boot on i386 systems with certain adapters using
the mpt driver, and also running the hugemem kernel. (BZ#533798)

* on certain hardware, the igb driver was unable to detect link statuses
correctly. This may have caused problems for network bonding, such as
failover not occurring. (BZ#534105)

* the RHSA-2009:1024 update introduced a regression. After updating to Red
Hat Enterprise Linux 4.8 and rebooting, network links often failed to be
brought up for interfaces using the forcedeth driver. "no link during
initialization" messages may have been logged. (BZ#534112)

* the RHSA-2009:1024 update introduced a second regression. On certain
systems, PS/2 keyboards failed to work. (BZ#537344)

* a bug in checksum offload calculations could have crashed the bnx2x
firmware when the iptable_nat module was loaded, causing network traffic
to stop. (BZ#537013)

* a check has been added to the IPv4 code to make sure that the routing
table data structure, rt, is not NULL, to help prevent future bugs in
functions that call ip_append_data() from being exploitable. (BZ#537016)

* possible kernel pointer dereferences on systems with several NFS mounts
(a mixture of "-o lock" and "-o nolock"), which in rare cases may have
caused a system crash, have been resolved. (BZ#537017)

Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
