An update that solves 23 vulnerabilities and has 43 fixes
is now available.

Description:


The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various
security and bugfixes.

Following feature was added to kernel-xen:
- A improved XEN blkfront module was added, which allows more I/O
bandwidth. (FATE#320200) It is called xen-blkfront in PV, and
xen-vbd-upstream in HVM mode.

The following security bugs were fixed:
- CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the
Linux kernel allowed local users to bypass intended AF_UNIX socket
permissions or cause a denial of service (panic) via crafted epoll_ctl
calls (bnc#955654).
- CVE-2015-7515: An out of bounds memory access in the aiptek USB driver
could be used by physical local attackers to crash the kernel
(bnc#956708).
- CVE-2015-7550: The keyctl_read_key function in security/keys/keyctl.c in
the Linux kernel did not properly use a semaphore, which allowed local
users to cause a denial of service (NULL pointer dereference and system
crash) or possibly have unspecified other impact via a crafted
application that leverages a race condition between keyctl_revoke and
keyctl_read calls (bnc#958951).
- CVE-2015-8539: The KEYS subsystem in the Linux kernel allowed local
users to gain privileges or cause a denial of service (BUG) via crafted
keyctl commands that negatively instantiate a key, related to
security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and
security/keys/user_defined.c (bnc#958463).
- CVE-2015-8543: The networking implementation in the Linux kernel did not
validate protocol identifiers for certain protocol families, which
allowed local users to cause a denial of service (NULL function pointer
dereference and system crash) or possibly gain privileges by leveraging
CLONE_NEWUSER support to execute a crafted SOCK_RAW application
(bnc#958886).
- CVE-2015-8550: Compiler optimizations in the XEN PV backend drivers
could have lead to double fetch vulnerabilities, causing denial of
service
or arbitrary code execution (depending on the configuration)
(bsc#957988).
- CVE-2015-8551, CVE-2015-8552: xen/pciback: For
XEN_PCI_OP_disable_msi[|x] only disable if device has MSI(X) enabled
(bsc#957990).
- CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in
drivers/net/ppp/pptp.c in the Linux kernel did not verify an address
length, which allowed local users to obtain sensitive information from
kernel memory and bypass the KASLR protection mechanism via a crafted
application (bnc#959190).
- CVE-2015-8575: The sco_sock_bind function in net/bluetooth/sco.c in the
Linux kernel did not verify an address length, which allowed local users
to obtain sensitive information from kernel memory and bypass the KASLR
protection mechanism via a crafted application (bnc#959190 bnc#959399).
- CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux kernel did not
properly manage the relationship between a lock and a socket, which
allowed local users to cause a denial of service (deadlock) via a
crafted sctp_accept call (bnc#961509).
- CVE-2015-8785: The fuse_fill_write_pages function in fs/fuse/file.c in
the Linux kernel allowed local users to cause a denial of service
(infinite loop) via a writev system call that triggers a zero length for
the first segment of an iov (bnc#963765).
- CVE-2015-8812: A use-after-free flaw was found in the CXGB3 kernel
driver when the network was considered to be congested. This could be
used by local attackers to cause machine crashes or potentially code
execution (bsc#966437).
- CVE-2016-0723: Race condition in the tty_ioctl function in
drivers/tty/tty_io.c in the Linux kernel allowed local users to obtain
sensitive information from kernel memory or cause a denial of service
(use-after-free and system crash) by making a TIOCGETD ioctl call during
processing of a TIOCSETD ioctl call (bnc#961500).
- CVE-2016-2069: Race conditions in TLB syncing was fixed which could leak
to information leaks (bnc#963767).
- CVE-2016-2384: Removed a double free in the ALSA usb-audio driver in the
umidi object which could lead to crashes (bsc#966693).
- CVE-2016-2543: Added a missing NULL check at remove_events ioctl in ALSA
that could lead to crashes. (bsc#967972).
- CVE-2016-2544, CVE-2016-2545, CVE-2016-2546, CVE-2016-2547,
CVE-2016-2548, CVE-2016-2549: Various race conditions in ALSAs timer
