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

These new kernel packages contain fixes for the security issues
described below :

* a flaw in the connection tracking support for SCTP that allowed a
remote user to cause a denial of service by dereferencing a NULL
pointer. (CVE-2007-2876, Important)

* a flaw in the mount handling routine for 64-bit systems that allowed
a local user to cause denial of service (crash). (CVE-2006-7203,
Important)

* a flaw in the IPv4 forwarding base that allowed a local user to
cause an out-of-bounds access. (CVE-2007-2172, Important)

* a flaw in the PPP over Ethernet implementation that allowed a local
user to cause a denial of service (memory consumption) by creating a
socket using connect and then releasing it before the PPPIOCGCHAN
ioctl has been called. (CVE-2007-2525, Important)

* a flaw in the fput ioctl handling of 32-bit applications running on
64-bit platforms that allowed a local user to cause a denial of
service (panic). (CVE-2007-0773, Important)

* a flaw in the NFS locking daemon that allowed a local user to cause
denial of service (deadlock). (CVE-2006-5158, Moderate)

* a flaw in the sysfs_readdir function that allowed a local user to
cause a denial of service by dereferencing a NULL pointer.
(CVE-2007-3104, Moderate)

* a flaw in the core-dump handling that allowed a local user to create
core dumps from unreadable binaries via PT_INTERP. (CVE-2007-0958,
Low)

* a flaw in the Bluetooth subsystem that allowed a local user to
trigger an information leak. (CVE-2007-1353, Low)

In addition, the following bugs were addressed :

* the NFS could recurse on the same spinlock. Also, NFS, under certain
conditions, did not completely clean up Posix locks on a file close,
leading to mount failures.

* the 32bit compatibility didn't return to userspace correct values
for the rt_sigtimedwait system call.

* the count for unused inodes could be incorrect at times, resulting
in dirty data not being written to disk in a timely manner.

* the cciss driver had an incorrect disk size calculation (off-by-one
error) which prevented disk dumps.

Red Hat would like to thank Ilja van Sprundel and the OpenVZ Linux
kernel team for reporting issues fixed in this erratum.

  - a flaw in the mount handling routine for 64-bit systems
    that allowed a local user to cause denial of service
    (crash). (CVE-2006-7203, Important)

  - a flaw in the IPv4 forwarding base that allowed a local
    user to cause an out-of-bounds access. (CVE-2007-2172,
    Important)

  - a flaw in the PPP over Ethernet implementation that
    allowed a local user to cause a denial of service
    (memory consumption) by creating a socket using connect
    and then releasing it before the PPPIOCGCHAN ioctl has
    been called. (CVE-2007-2525, Important)

  - a flaw in the fput ioctl handling of 32-bit applications
    running on 64-bit platforms that allowed a local user to
    cause a denial of service (panic). (CVE-2007-0773,
    Important)

  - a flaw in the NFS locking daemon that allowed a local
    user to cause denial of service (deadlock).
    (CVE-2006-5158, Moderate)

  - a flaw in the sysfs_readdir function that allowed a
    local user to cause a denial of service by dereferencing
    a NULL pointer. (CVE-2007-3104, Moderate)

  - a flaw in the core-dump handling that allowed a local
    user to create core dumps from unreadable binaries via
    PT_INTERP. (CVE-2007-0958, Low)

  - a flaw in the Bluetooth subsystem that allowed a local
    user to trigger an information leak. (CVE-2007-1353,
    Low)

In addition, the following bugs were addressed :

  - the NFS could recurse on the same spinlock. Also, NFS,
    under certain conditions, did not completely clean up
    Posix locks on a file close, leading to mount failures.

  - the 32bit compatibility didn't return to userspace
    correct values for the rt_sigtimedwait system call.

  - the count for unused inodes could be incorrect at times,
    resulting in dirty data not being written to disk in a
    timely manner.

  - the cciss driver had an incorrect disk size calculation
    (off-by-one error) which prevented disk dumps.

NOTE1: From The Upstream Vendors release notes 'During PCI probing,
Red Hat Enterprise Linux 4 Update 5 attempts to use information
obtained from MCFG (memory-mapped PCI configuration space). On
AMD-systems, this type of access does not work on some buses, as the
kernel cannot parse the MCFG table.

To work around this, add the parameter pci=conf1 or pci=nommconf on
the kernel boot line in /etc/grub.conf. For example :

title Red Hat Enterprise Linux AS (2.6.9-42.0.2.EL) root (hd0,0)
kernel /vmlinuz-2.6.9-42.0.2.EL ro root=/dev/VolGroup00/LogVol00 rhgb
quiet pci=conf1 initrd /initrd-2.6.9-42.0.2.EL.img

Doing this instructs the kernel to use PCI Conf1 access instead of
MCFG-based access.'

NOTE2: From The Upstream Vendors Knowledge Base 'Why did the ordering
of my NIC devices change in Red Hat Enterprise Linux 4.5?

The 2.6.9-55 version of the Red Hat Enterprise Linux 4 kernel (Update
5) reverts to the 2.4 ordering of network interface cards (NICs) on
certain systems. Note that if the 'HWADDR=MAC ADDRESS' line is present
in the /etc/sysconfig/network-scripts/ifcfg-ethX files, the NIC
ordering will not change.

To restore the original 2.6 ordering, which is different from the 2.4
ordering, boot with the option pci=nobfsort '"

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