Linux Kernel: Security/Bugfix update to 2.6.37.6

[Lighty]

Diese Aktualisierung wird für eine Behebung eines mit dem Paket verbundenen Sicherheitsrisikos benötigt.
The openSUSE 11.4 kernel was updated to 2.6.37.6 fixing
lots of bugs and security issues.

Following security issues have been fixed: CVE-2011-1493:
In the rose networking stack, when parsing the
FAC_NATIONAL_DIGIS facilities field, it was possible for a
remote host to provide more digipeaters than expected,
resulting in heap corruption. Check against ROSE_MAX_DIGIS
to prevent overflows, and abort facilities parsing on
failure.

CVE-2011-1182: Local attackers could send signals to their
programs that looked like coming from the kernel,
potentially gaining privileges in the context of setuid
programs.

CVE-2011-1478: An issue in the core GRO code where an skb
belonging to an unknown VLAN is reused could result in a
NULL pointer dereference.

CVE-2011-1476: Specially crafted requests may be written to
/dev/sequencer resulting in an underflow when calculating a
size for a copy_from_user() operation in the driver for
MIDI interfaces. On x86, this just returns an error, but it
could have caused memory corruption on other architectures.
Other malformed requests could have resulted in the use of
uninitialized variables.

CVE-2011-1477: Due to a failure to validate user-supplied
indexes in the driver for Yamaha YM3812 and OPL-3 chips, a
specially crafted ioctl request could have been sent to
/dev/sequencer, resulting in reading and writing beyond the
bounds of heap buffers, and potentially allowing privilege
escalation.

CVE-2011-0191: A information leak in the XFS geometry calls
could be used by local attackers to gain access to kernel
information.

CVE-2011-0711: A stack memory information leak in the xfs
FSGEOMETRY_V1 ioctl was fixed.

CVE-2011-0521: The dvb_ca_ioctl function in
drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel did
not check the sign of a certain integer field, which
allowed local users to cause a denial of service (memory
corruption) or possibly have unspecified other impact via a
negative value.

CVE-2011-1010: The code for evaluating Mac partitions (in
fs/partitions/mac.c) contained a bug that could crash the
kernel for certain corrupted Mac partitions.

CVE-2011-0712: Multiple buffer overflows in the caiaq
Native Instruments USB audio functionality in the Linux
kernel might have allowed attackers to cause a denial of
service or possibly have unspecified other impact via a
long USB device name, related to (1) the
snd_usb_caiaq_audio_init function in
sound/usb/caiaq/audio.c and (2) the snd_usb_caiaq_midi_init
function in sound/usb/caiaq/midi.c.

CVE-2011-1013: A signedness issue in the drm ioctl handling
could be used by local attackers to potentially overflow
kernel buffers and execute code.

CVE-2011-1082: The epoll subsystem in Linux did not prevent
users from creating circular epoll file structures,
potentially leading to a denial of service (kernel
deadlock).

CVE-2010-4650: A kernel buffer overflow in the cuse server
module was fixed, which might have allowed local privilege
escalation. However only CUSE servers could exploit it and
/dev/cuse is normally restricted to root.

CVE-2011-1093: A bug was fixed in the DCCP networking stack
where the order of dccp_rcv_state_process() still permitted
reception even after closing the socket. A Reset after
close thus causes a NULL pointer dereference by not
preventing operations on an already torn-down socket.

CVE-2011-1163: The code for evaluating OSF partitions (in
fs/partitions/osf.c) contained a bug that leaks data from
kernel heap memory to userspace for certain corrupted OSF
partitions.

CVE-2011-1012: The code for evaluating LDM partitions (in
fs/partitions/ldm.c) contained a bug that could crash the
kernel for certain corrupted LDM partitions.

CVE-2011-1581: Doing bridging with devices with more than
16 receive queues could crash the kernel.

CVE-2011-1160: Kernel information via the TPM devices could
by used by local attackers to read kernel memory.

CVE-2011-1577: The Linux kernel automatically evaluated
partition tables of storage devices. The code for
evaluating EFI GUID partitions (in fs/partitions/efi.c)
contained a bug that causes a kernel oops on certain
corrupted GUID partition tables, which might be used by
local attackers to crash the kernel or potentially execute
code.

CVE-2011-1180: In the IrDA module, length fields provided
by a peer for names and attributes may be longer than the
destination array sizes and were not checked, this allowed
local attackers (close to the irda port) to potentially
corrupt memory.

CVE-2011-1016: The Radeon GPU drivers in the Linux kernel
did not properly validate data related to the AA resolve
registers, which allowed local users to write to arbitrary
memory locations associated with (1) Video RAM (aka VRAM)
or (2) the Graphics Translation Table (GTT) via crafted
values.
