"The openSUSE 11.1 Kernel was updated to 2.6.27.39 fixing various bugs
and security issues.

Following security issues have been fixed: CVE-2009-3547: A race
condition during pipe open could be used by local attackers to cause a
denial of service. (Due to mmap_min_addr protection enabled by
default, code execution is not possible.)

CVE-2009-2910: On x86_64 systems a information leak of high register
contents (upper 32bit) was fixed.

CVE-2009-2903: Memory leak in the appletalk subsystem in the Linux
kernel when the appletalk and ipddp modules are loaded but the
ipddp'N' device is not found, allows remote attackers to cause a
denial of service (memory consumption) via IP-DDP datagrams.

CVE-2009-3621: net/unix/af_unix.c in the Linux kernel allows local
users to cause a denial of service (system hang) by creating an
abstract-namespace AF_UNIX listening socket, performing a shutdown
operation on this socket, and then performing a series of connect
operations to this socket.

CVE-2009-3612 / CVE-2005-4881: The tcf_fill_node function in
net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x
before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a
certain tcm__pad2 structure member, which might allow local users to
obtain sensitive information from kernel memory via unspecified
vectors. NOTE: this issue existed because of an incomplete fix for
CVE-2005-4881.

CVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux kernel
does not properly verify Concurrent Command Engine (CCE) state
initialization, which allows local users to cause a denial of service
(NULL pointer dereference and system crash) or possibly gain
privileges via unspecified ioctl calls.

CVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the
NFSv4 client in the Linux kernel allows remote NFS servers to cause a
denial of service (NULL pointer dereference and panic) by sending a
certain response containing incorrect file attributes, which trigger
attempted use of an open file that lacks NFSv4 state.

CVE-2009-3286: Sv4 in the Linux kernel does not properly clean up an
inode when an O_EXCL create fails, which causes files to be created
with insecure settings such as setuid bits, and possibly allows local
users to gain privileges, related to the execution of the
do_open_permission function even when a create fails."
