"The Linux kernel on SUSE Linux Enterprise 11 was updated to 2.6.27.23
and received lots of bugs and security fixes.

The following security issues have been fixed :

  - Buffer overflow in fs/cifs/connect.c in CIFS in the
    Linux kernel 2.6.29 and earlier allows remote attackers
    to cause a denial of service (crash) or potential code
    execution via a long nativeFileSystem field in a Tree
    Connect response to an SMB mount request.
    (CVE-2009-1439)

This requires that kernel can be made to mount a 'cifs' filesystem
from a malicious CIFS server.

  - The exit_notify function in kernel/exit.c in the Linux
    kernel did not restrict exit signals when the CAP_KILL
    capability is held, which allows local users to send an
    arbitrary signal to a process by running a program that
    modifies the exit_signal field and then uses an exec
    system call to launch a setuid application.
    (CVE-2009-1337)

The GCC option -fwrapv has been added to compilation to work around
potentially removing integer overflow checks.

  - Integer overflow in rose_sendmsg (sys/net/af_rose.c) in
    the Linux kernel might allow attackers to obtain
    sensitive information via a large length value, which
    causes 'garbage' memory to be sent. (CVE-2009-1265)

  - The vmx_set_msr function in arch/x86/kvm/vmx.c in the
    VMX implementation in the KVM subsystem in the Linux
    kernel on the i386 platform allows guest OS users to
    cause a denial of service (OOPS) by setting the EFER_LME
    (aka 'Long mode enable') bit in the Extended Feature
    Enable Register (EFER) model-specific register, which is
    specific to the x86_64 platform. (CVE-2009-1242)

  - The __inet6_check_established function in
    net/ipv6/inet6_hashtables.c in the Linux kernel, when
    Network Namespace Support (aka NET_NS) is enabled,
    allows remote attackers to cause a denial of service
    (NULL pointer dereference and system crash) via vectors
    involving IPv6 packets. (CVE-2009-1360)

  - drivers/char/agp/generic.c in the agp subsystem in the
    Linux kernel does not zero out pages that may later be
    available to a user-space process, which allows local
    users to obtain sensitive information by reading these
    pages. (CVE-2009-1192)

Additionaly a lot of bugs have been fixed and are listed in the RPM
changelog."
