"This kernel update fixes the following security problems :

  - CVE-2007-3105: Stack-based buffer overflow in the random
    number generator (RNG) implementation in the Linux
    kernel before 2.6.22 might allow local root users to
    cause a denial of service or gain privileges by setting
    the default wake-up threshold to a value greater than
    the output pool size, which triggers writing random
    numbers to the stack by the pool transfer function
    involving 'bound check ordering'. Since this value can
    only be changed by a root user, exploitability is low.

  - CVE-2007-2525: A memory leak in the PPPoE driver can be
    abused by local users to cause a denial-of-service
    condition.

  - CVE-2007-3851: On machines with a Intel i965 based
    graphics card local users with access to the direct
    rendering devicenode could overwrite memory on the
    machine and so gain root privileges.

  - CVE-2007-4573: It was possible for local user to become
    root by exploitable a bug in the IA32 system call
    emulation. This affects x86_64 platforms with kernel
    2.4.x and 2.6.x before 2.6.22.7 only.

  - CVE-2007-4571: An information disclosure vulnerability
    in the ALSA driver can be exploited by local users to
    read sensitive data from the kernel memory.

    value:
"This kernel update fixes the following security problems :

  - The IPv6 protocol allows remote attackers to cause a
    denial of service via crafted IPv6 type 0 route headers
    (IPV6_RTHDR_TYPE_0) that create network amplification
    between two routers. (CVE-2007-2242)

    The default is that RH0 is disabled now. To adjust this,
    write to the file /proc/net/accept_source_route6.

  - The random number feature in the Linux kernel 2.6 (1)
    did not properly seed pools when there is no entropy, or
    (2) used an incorrect cast when extracting entropy,
    which might have caused the random number generator to
    provide the same values after reboots on systems without
    an entropy source. (CVE-2007-2453)

  - A NULL pointer dereference in SCTP connection tracking
    could be caused by a remote attacker by sending
    specially crafted packets. Note that this requires SCTP
    set-up and active to be exploitable. (CVE-2007-2876)

  - Stack-based buffer overflow in the random number
    generator (RNG) implementation in the Linux kernel
    before 2.6.22 might allow local root users to cause a
    denial of service or gain privileges by setting the
    default wakeup threshold to a value greater than the
    output pool size, which triggers writing random numbers
    to the stack by the pool transfer function involving
    'bound check ordering'. (CVE-2007-3105)

    Since this value can only be changed by a root user,
    exploitability is low.

  - The signal handling in the Linux kernel, when run on
    PowerPC systems using HTX, allows local users to cause a
    denial of service via unspecified vectors involving
    floating point corruption and concurrency.
    (CVE-2007-3107)

  - Memory leak in the PPP over Ethernet (PPPoE) socket
    implementation in the Linux kernel allowed local users
    to cause a denial of service (memory consumption) by
    creating a socket using connect, and releasing it before
    the PPPIOCGCHAN ioctl is initialized. (CVE-2007-2525)

  - The lcd_write function in drivers/usb/misc/usblcd.c in
    the Linux kernel did not limit the amount of memory used
    by a caller, which allowed local users to cause a denial
    of service (memory consumption). (CVE-2007-3513)

  - A local attacker could send a death signal to a setuid
    root program under certain conditions, potentially
    causing unwanted behaviour in this program.
    (CVE-2007-3848)

  - On machines with a Intel i965 based graphics card local
    users with access to the direct rendering devicenode
    could overwrite memory on the machine and so gain root
    privileges. (CVE-2007-3851)

  - Fixed a denial of service possibility where a local
    attacker with access to a pwc camera device could hang
    the USB subsystem. [#302194]

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

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

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.

All Red Hat Enterprise Linux 4 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum."
